In addition, E C R circuit techniques are added that give the C TLC2654 and TLC2654A superior noise perfor- NC – No internal connection mance. Chopper-stabilization techniques provide for extremely high dc precision by continuously nulling input offset voltage even during variations in temperature, time, common-mode voltage, and power-supply voltage. The high chopping frequency of the TLC2654 and TLC2654A (see Figure 1) provides excellent noise performance in a frequency spectrum from near dc to 10 kHz. In addition, intermodulation or aliasing error is eliminated from frequencies up to 5 kHz. This high dc precision and low noise, coupled with the extremely high input impedance of the CMOS input stage, makes the TLC2654 and TLC2654A ideal choices for a broad range of applications such as low-level, low-frequency thermocouple amplifiers and strain gauges and wide-bandwidth and subsonic circuits. For applications requiring even greater dc precision, use the TLC2652 or TLC2652A devices, which have a chopping frequency of 450 Hz.

TLC2654, TLC2654A Advanced LinCMOS LOW-NOISE CHOPPER-STABILIZED OPERATIONAL AMPLIFIERS SLOS020G – NOVEMBER 1988 – REVISED APRIL 2001 description (continued) EQUIVALENT INPUT NOISE VOLTAGE vs The TLC2654 and TLC2654A common-mode FREQUENCY input voltage range includes the negative rail, 10 k thereby providing superior performance in either VZHz X single-supply or split-supply applications, even at X power supply voltage levels as low as ±2.3 V. nV/nV/ – Two external capacitors are required to operate ge a 1 k the device; however, the on-chip chopper-control olt V circuitry is transparent to the user. On devices in e Typical 250-Hz s the 14-pin and 20-pin packages, the control oi Chopper-Stabilized circuitry is accessible, allowing the user the option ut N Operational Amplifier of controlling the clock frequency with an external p n frequency source. In addition, the clock threshold nt I 100 of the TLC2554 and TLC2654A requires no level ale TLC2654 v shifting when used in the single-supply configura- ui q tion with a normal CMOS or TTL clock input. E – n n Innovative circuit techniques used on the VV 10 TLC2654 and TLC2654A allow exceptionally fast 1 10 100 1 k overload recovery time. An output clamp pin is f – Frequency – Hz available to reduce the recovery time even further. Figure 1 The device inputs and outputs are designed to withstand –100-mA surge currents without sustaining latch-up. In addition, the TLC2654 and TLC2654A incorporate internal ESD-protection circuits that prevent functional failures at voltages up to 2000 V as tested under MIL-STD-883C, Method 3015; however, exercise care in handling these devices, as exposure to ESD may result in degradation of the device parametric performance. The C-suffix devices are characterized for operation from 0°C to 70°C. The I-suffix devices are characterized for operation from –40°C to 85°C. The Q-suffix devices are characterized for operation from –40°C to 125°C. The M-suffix devices are characterized for operation over the full military temperature range of –55°C to125°C.

TLC2654, TLC2654A Advanced LinCMOS LOW-NOISE CHOPPER-STABILIZED OPERATIONAL AMPLIFIERS SLOS020G – NOVEMBER 1988 – REVISED APRIL 2001 APPLICATION INFORMATION capacitor selection and placement Leakage and dielectric absorption are the two important factors to consider when selecting external capacitors C and C . Both factors can cause system degradation, negating the performance advantages realized by XA XB using the TLC2654. Degradation from capacitor leakage becomes more apparent with increasing temperatures. Low-leakage capacitors and standoffs are recommended for operation at T = 125°C. In addition, guard bands are A recommended around the capacitor connections on both sides of the printed-circuit board to alleviate problems caused by surface leakage on circuit boards. Capacitors with high dielectric absorption tend to take several seconds to settle upon application of power, which directly affects input offset voltage. In applications needing fast settling of input voltage, high-quality film capacitors such as mylar, polystyrene, or polypropylene should be used. In other applications, a ceramic or other low-grade capacitor can suffice. Unlike many choppers available today, the TLC2654 is designed to function with values of CXA and CXB in the range of 0.1 µF to 1 µF without degradation to input offset voltage or input noise voltage. These capacitors should be located as close as possible to C and C and return to either V or C RETURN. On many XA XB DD– choppers, connecting these capacitors to VDD– causes degradation in noise performance; this problem is eliminated on the TLC2654. internal/external clock The TLC2654 has an internal clock that sets the chopping frequency to a nominal value of 10 kHz. On 8-pin packages, the chopping frequency can only be controlled by the internal clock; however, on all 14-pin packages and the 20-pin FK package the device chopping frequency can be set by the internal clock or controlled externally by use of the INT/EXT and CLK IN. To use the internal 10-kHz clock, no connection is necessary. If external clocking is desired, connect INT/EXT to VDD– and the external clock to CLK IN. The external clock trip point is 2.5 V above the negative rail; however, CLK IN can be driven from the negative rail to 5 V above the negative rail. This allows the TLC2654 to be driven directly by 5-V TTL and CMOS logic when operating in the single-supply configuration. If this 5-V level is exceeded, damage could occur to the device unless the current into CLK IN is limited to ±5 mA.

TLC2654, TLC2654A Advanced LinCMOS LOW-NOISE CHOPPER-STABILIZED OPERATIONAL AMPLIFIERS SLOS020G – NOVEMBER 1988 – REVISED APRIL 2001 APPLICATION INFORMATION overload recovery/output clamp (continued) The clamp is a switch that is automatically activated when the output is approximately 1 V from either supply rail. When connected to the inverting input (in parallel with the closed-loop feedback resistor), the closed-loop gain is reduced and the TLC2654 output is prevented from going into saturation. Since the output must source or sink current through the switch (see Figure 9), the maximum output voltage swing is slightly reduced. thermoelectric effects To take advantage of the extremely low offset voltage temperature coefficient of the TLC2654, care must be taken to compensate for the thermoelectric effects present when two dissimilar metals are brought into contact with each other (such as device leads being soldered to a printed-circuit board). It is not uncommon for dissimilar metal junctions to produce thermoelectric voltages in the range of several microvolts per degree Celsius (orders of magnitude greater than the 0.01 µV/°C typical of the TLC2654). To help minimize thermoelectric effects, pay careful attention to component selection and circuit-board layout. Avoid the use of nonsoldered connections (such as sockets, relays, switches, etc.) in the input signal path. Cancel thermoelectric effects by duplicating the number of components and junctions in each device input. The use of low-thermoelectric-coefficient components, such as wire-wound resistors, is also beneficial. latch-up avoidance Because CMOS devices are susceptible to latch-up due to their inherent parasitic thyristors, the TLC2654 inputs and outputs are designed to withstand –100-mA surge currents without sustaining latch-up; however, techniques to reduce the chance of latch-up should be used whenever possible. Internal protection diodes should not, by design, be forward biased. Applied input and output voltages should not exceed the supply voltage by more than 300 mV. Care should be exercised when using capacitive coupling on pulse generators. Supply transients should be stunted by the use of decoupling capacitors (0.1 µF typical) located across the supply rails as close to the device as possible. The current path established if latch-up occurs is usually between the supply rails and is limited only by the impedance of the power supply and the forward resistance of the parasitic thyristor. The chance of latch-up occurring increases with increasing temperature and supply voltage. electrostatic-discharge protection The TLC2654 incorporates internal ESD-protection circuits that prevent functional failures at voltages at or below 2000 V. Care should be exercised in handling these devices, as exposure to ESD may result in degradation of the device parametric performance. theory of operation Chopper-stabilized operational amplifiers offer the best dc performance of any monolithic operational amplifier. This superior performance is the result of using two operational amplifiers — a main amplifier and a nulling amplifier – plus oscillator-controlled logic and two external capacitors to create a system that behaves as a single amplifier. With this approach, the TLC2654 achieves submicrovolt input offset voltage, submicrovolt noise voltage, and offset voltage variations with temperature in the nV/°C range. The TLC2654 on-chip control logic produces two dominant clock phases: a nulling phase and an amplifying phase. The term chopper-stabilized derives from the process of switching between these two clock phases. Figure 35 shows a simplified block diagram of the TLC2654. Switches A and B are make-before-break types. POST OFFICE BOX 655303 • DALLAS, TEXAS 75265 21

TLC2654, TLC2654A Advanced LinCMOS LOW-NOISE CHOPPER-STABILIZED OPERATIONAL AMPLIFIERS SLOS020G – NOVEMBER 1988 – REVISED APRIL 2001 APPLICATION INFORMATION theory of operation (continued) During the nulling phase, switch A is closed, shorting the nulling amplifier inputs together and allowing the nulling amplifier to reduce its own input offset voltage by feeding its output signal back to an inverting input node. Simultaneously, external capacitor CXA stores the nulling potential to allow the offset voltage of the amplifier to remain nulled during the amplifying phase.

TLC2654 Simplified Block Diagram During the amplifying phase, switch B is closed, connecting the output of the nulling amplifier to a noninverting input of the main amplifier. In this configuration, the input offset voltage of the main amplifier is nulled. Also, external capacitor C stores the nulling potential to allow the offset voltage of the main amplifier to remain XB nulled during the next nulling phase. This continuous chopping process allows offset voltage nulling during variations in time and temperature and over the common-mode input voltage range and power supply range. In addition, because the low-frequency signal path is through both the null and main amplifiers, extremely high gain is achieved. The low-frequency noise of a chopper amplifier depends on the magnitude of the component noise prior to chopping and the capability of the circuit to reduce this noise while chopping. The use of the Advanced LinCMOS process, with its low-noise analog MOS transistors and patent-pending input stage design, significantly reduces the input noise voltage. The primary source of nonideal operation in chopper-stabilized amplifiers is error charge from the switches. As charge imbalance accumulates on critical nodes, input offset voltage can increase especially with increasing chopping frequency. This problem has been significantly reduced in the TLC2654 by use of a patent-pending compensation circuit and the Advanced LinCMOS process. The TLC2654 incorporates a feed-forward design that ensures continuous frequency response. Essentially, the gain magnitude of the nulling amplifier and compensation network crosses unity at the break frequency of the main amplifier. As a result, the high-frequency response of the system is the same as the frequency response of the main amplifier. This approach also ensures that the slewing characteristics remain the same during both the nulling and amplifying phases. The primary limitation on ac performance is the chopping frequency. As the input signal frequency approaches the chopper’s clock frequency, intermodulation (or aliasing) errors result from the mixing of these frequencies. To avoid these error signals, the input frequency must be less than half the clock frequency. Most choppers available today limit the internal chopping frequency to less than 500 Hz in order to eliminate errors due to the charge imbalancing phenomenon mentioned previously. However, to avoid intermodulation errors on a 500-Hz chopper, the input signal frequency must be limited to less than 250 Hz. 22 POST OFFICE BOX 655303 • DALLAS, TEXAS 75265

TLC2654, TLC2654A Advanced LinCMOS LOW-NOISE CHOPPER-STABILIZED OPERATIONAL AMPLIFIERS SLOS020G – NOVEMBER 1988 – REVISED APRIL 2001 APPLICATION INFORMATION theory of operation (continued) The TLC2654 removes this restriction on ac performance by using a 10-kHz internal clock frequency. This high chopping frequency allows amplification of input signals up to 5 kHz without errors due to intermodulation and greatly reduces low-frequency noise. THERMAL INFORMATION temperature coefficient of input offset voltage Figure 36 shows the effects of package-included thermal EMF. The TLC2654 can null only the offset voltage within its nulling loop. There are metal-to-metal junctions outside the nulling loop (bonding wires, solder joints, etc.) that produce EMF. In Figure 36, a TLC2654 packaged in a 14-pin plastic package (N package) was placed in an oven at 25°C at t = 0, biased up, and allowed to stabilize. At t = 3 min, the oven was turned on and allowed to rise in temperature to 125°C. As evidenced by the curve, the overall change in input offset voltage with temperature is less than the specified maximum limit of 0.05 µV/°C. 8 0.08 4 0.04 0.1 µF µVoltage –V – 40 0– 0.04 Coefficient of°µage – uV/CV/C 50 kΩ – Input Offset O –– 1 28 –– 00..0182 O – Temperature OInput Offset Volt IINN–+ 45100 Ω +– –55 VV VIO1 =0 VOOU/1T000 VI – 15 – 0.16 αaVIVI 0.1 µF 50 kΩ VO – 18 – 0.2 0 3 6 9 12 15 18 21 24 27 30 t – Time – min Pin numbers shown are for the D (14-pin), J, and N packages.
