ICL7652 Advanced LinCMOSTM PRECISION CHOPPER-STABILIZED OPERATIONAL AMPLIFIER TYPICAL APPLICATION DATA capacitor selection and placement The two important factors to consider when selecting external capacitors CXA and CXB are leakage and dielectric absorption. Both factors can cause system degradation that negate the performance advantages realized by using the ICL7652. Degradation from capacitor leakage becomes more apparent with increasing temperatures. Low-leakage capacitors and standoffs are recommended for operation at T A = 125°C. In addition, guardbands around the capacitor connections on both sides of the printed circuit board are recommended 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 offset voltage, it is recommended that high-quality film capacitors, such as mylar, polystyrene, or polypropylene, be used. In other applications, however, a ceramic or other low-grade capacitor may suffice. Unlike many choppers available today, the ICL7652 is designed to function with values of CXA and CXB in the range of 0.1 ~F to 1 ~F without degradation to input offset voltage or input noise voltage. These capacitors should be located as close as possible to the CXA and CXB pins and returned to either the VDD- pin or the C RETURN pin. Note that on many choppers, connecting these capacitors to the VDD- pin causes degradation in noise performance, a problem that is eliminated on the ICL7652. overload recovery/output clamp When large differential input voltage conditions are applied to the ICL7652, the nulling loop attempts to prevent the output from saturating by driving CXA and CXB to internally-clamped voltage levels. Once the overdrive condition is removed, a period of time is required to allow the built-up charge to dissipate. This time period is defined as overload recovery time (see Figure 25). Typical overload recovery time for the ICL7652 is significantly faster than that of competitive products. thermoelectric effects T o take advantage of the extremely low offset voltage temperature coefficient of the ICL7652, 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 O.O1-!lV/OC typical of the ICL7652). To help minimize thermoelectric effects, careful attention should be paid 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- FIGURE 25. OVERLOAD RECOVERY coefficient components, such as wire-wound resistors, is also beneficial. TEXAS ~ 12 INSTRUMENTS POST OFFICE BOX 655303 .DALLAS. TEXAS 75265

ICL7652 Advanced LinCMOSTM PRECISION CHOPPER-STABILIZED OPERATIONAL AMPLIFIER TYPICAL APPLICATION DATA avoiding latchup The ICL7652 inputs and output are designed to withstand -1 OO-mA surge currents without sustaining latchup. However, because CMOS devices are susceptible to latchup due to their inherent parasitic thyristors, techniques to reduce the chance of latchup should be used whenever possible. Internal protection diodes should not be forward biased in normal operation. 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 shunted by using decoupling capacitors (0.1 ~F typical) located across the supply rails as close to the device as possible. The current path established if latchup 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 latchup occurring increases with increasing temperature and supply voltage. electrostatic discharge protection The ICL7652 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 ICL7652 achieves submicrovolt input offset voltage, submicrovolt noise voltage, and offset voltage variations with temperature in the nV/OC range. The ICL7652 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 26 shows a simplified block diagram of the ICL7652. Switches A and B are make-before-break types. 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. During the amplifying phase, switch B is closed, MAIN connecting the output of the nulling amplifier to a IN + , noninverting input of the main amplifier. In this configuration, the input offset voltage of the main IN - -;r>- Vo amplifier is nulled. Also, external capacitor CXB B D stores the nulling potential to allow the offset A voltage of the main amplifier to remain nulled ">-- ~~ ~ during the next nulling phase.

ICL7652 Advanced LinCMOSTM PRECISION CHOPPER-STABILIZED OPERATIONAL AMPLIFIER TYPICAL APPLICA TION DA T A 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 linCMOSTM 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 ICl7652 by use of a patent-pending compensation circuit and the Advanced linCMOSTM process. The ICl7652 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. temperature coefficient of input offset voltage Figure 27 shows the effects of package-induced thermal EMF. The ICL7652 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 27, an ICL7652 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 much less than the specified maximum limit of 0.05 !lV/OC. 0.1 ~F -1t- 50kQ -'\/v'v- 10 ~ 5Y t VIO = VO/1000 1+ -5Y YO 0.1 ~F 50 kQ + FIGURE 27.
