It is simply a string of resistors, each of value R. The code loaded into the DAC register determines at which node on the string the voltage is tapped off to be fed into the output amplifier by closing one of the switches connecting the string to the amplifier. The resistor string architecture results in monotonicity. The R switch is controlled by the gain registers (see the Gain Function DIVIDER section). Because the output amplifier has a gain of 2, R is not shorted when the DAC-n gain is set to 1 DIVIDER (default if internal reference is disabled), and is shorted when the DAC-n gain is set to 2 (default if internal referenceisenabled). V /V REFIN REFOUT R DIVIDER V REF 2 R R To OutputAmplifier R R Figure89. ResistorString 8.3.1.2 OutputAmplifier The output buffer amplifier is capable of generating rail-to-rail voltages on its output, giving a maximum output range of 0 V to AV . It is capable of driving a load of 2 kΩ in parallel with 3 nF to GND. The typical slew rate is DD 0.75 V/µs, with a typical full-scale settling time of 14 µs as shown in Figure 31, Figure 32, Figure 75 and Figure76.

All device registers are reset as shown in Table 4. At power up, all DAC registers are filled with zeros and the output voltages of all DAC channels are set to zero volts. Each DAC channel remains that way until a valid load command is written to it. The power-on reset is useful in applications where it is important to knowthestateoftheoutputofeachDACwhilethedeviceisintheprocessofpoweringup.Nodevicepinshould be brought high before applying power to the device. The internal reference is disabled by default and remains thatwayuntilavalidreference-changecommandisexecuted. 8.3.3.2 Power-OnResettoMid-Scale The DAC7563, DAC8163, and DAC8563 devices contain a power-on reset circuit that controls the output voltage during power up. At power up, all DAC registers are reset to mid-scale code and the output voltages of all DAC channels are set to V / 2 volts. Each DAC channel remains that way until a valid load command is written to REFIN it. The power-on reset is useful in applications where it is important to know the state of the output of each DAC while the device is in the process of powering up. No device pin should be brought high before applying power to the device. The internal reference is powered off or down by default and remains that way until a valid reference- change command is executed. If using an external reference, it is acceptable to power on the V pin either at REFIN thesametimeasorafterapplyingAV .

The POR circuit requires specific AV levels, as indicated in Figure 91, to ensure discharging of internal capacitors and to reset DD the device on power up. In order to ensure a power-on reset, AV must be below 0.7 V for at least 1 ms. When DD AV drops below 2.2 V but remains above 0.7 V (shown as the undefined region), the device may or may not DD reset under all specified temperature and power-supply conditions.

One set is for the DAC channels and the other set is for the internal reference. The internal reference is forced to a powered-down state while both DAC channels are powered down, and is only enabled if any DAC channel is also in the normal mode of operation. For more information on the internal reference control, see the Internal ReferenceEnableRegistersection. 8.4.1.1 DACPower-DownCommands The DAC756x, DAC816x, and DAC856x DACs use four modes of operation. These modes are accessed by setting the serial interface command bits to 100. Once the command bits are set correctly, the four different power-down modes are software programmable by setting bits DB5 and DB4 in the shift register.

The gain for each channel, in Equation 2, is either 1 or 2. This gain is automatically set to 2 when using the internal reference, and is automatically set to 1 when the internal reference is disabled (default). However, each channel can have either gain by setting the registers appropriately. The gain registers are accessible by setting the serial interface command bits to 000, address bits to 010, and using DB1 for DAC-B and DB0 for DAC-A.

The internal reference can be powered up and powered down by setting the serial interface command bits to 111 and configuring DB0 (see Table 9). The internal reference is forced to a powered down state while both DAC channels are powered down, and can only be enabled if any DAC channel is in normal mode of operation. During the time that the internal reference is disabled, the DAC functions normally using an external reference. At this point, the internal reference is disconnectedfromtheV /V pin(Hi-Zoutput).

When the CLR pin receives a falling edge signal the clear mode is activated and changes the DAC output voltages accordingly. The device exits clear mode on the 24th falling edge of the next write to the device.

The DAC double-buffered architecture has been designed so that new data can be entered for eachDACwithoutdisturbingtheanalogoutputs. DAC756x, DAC816x, and DAC856x data updates can be performed either in synchronous or in asynchronous mode. In asynchronous mode, the LDAC pin is used as a negative edge-triggered timing signal for simultaneous DAC updates. Multiple single-channel writes can be done in order to set different channel buffers to desired values and then make a falling edge on LDAC pin to simultaneously update the DAC output registers. Data buffers of all channels must be loaded with desired data before an LDAC falling edge. After a high-to-low LDAC transition, all DACs are simultaneously updated with the last contents of the corresponding data buffers. If the content of a data buffer is not changed, the corresponding DAC output remains unchanged after the LDAC pin is triggered. LDACmustbereturnedhighbeforethenextserialcommandisinitiated. In synchronous mode, data are updated with the falling edge of the 24th SCLK cycle, which follows a falling edge of SYNC. For such synchronous updates, the LDAC pin is not required, and it must be connected to GND permanentlyorassertedandheldlowbeforesendingcommandstothedevice. Alternatively, all DAC outputs can be updated simultaneously using the built-in software function of LDAC. The LDACregisteroffersadditionalflexibilityandcontrolbyallowingtheselectionofwhichDACchannel(s)shouldbe updated simultaneously when the LDAC pin is being brought low. The LDAC register is loaded with a 2-bit word (DB1andDB0)usingcommandbitsC2,C1,andC0(seeTable17).Thedefaultvalueforeachbit,andtherefore for each DAC channel, is zero. If the LDAC register bit is set to 1, it overrides the LDAC pin (the LDAC pin is internally tied low for that particular DAC channel) and this DAC channel updates synchronously after the falling edge of the 24th SCLK cycle. However, if the LDAC register bit is set to 0, the DAC channel is controlled by the LDACpin. The combination of software and hardware simultaneous update functions is particularly useful in applications when updating a DAC channel, while keeping the other channel unaffected; see Table 11 and Table 17 for more information.

See the Serial WriteOperationtimingdiagram(Figure1)foranexampleofatypicalwritesequence. The DAC756x, DAC816x, or DAC856x input shift register is 24 bits wide, consisting of two don’t care bits (DB23 to DB22), three command bits (DB21 to DB19), three address bits (DB18 to DB16), and 16 data bits (DB15 to DB0). All 24 bits of data are loaded into the DAC under the control of the serial clock input, SCLK. DB23 (MSB) is the first bit that is loaded into the DAC shift register. DB23 is followed by the rest of the 24-bit word pattern, left-aligned. This configuration means that the first 24 bits of data are latched into the shift register, and any furtherclockingofdataisignored. The write sequence begins by bringing the SYNC line low. Data from the D line are clocked into the 24-bit shift IN register on each falling edge of SCLK. The serial clock frequency can be as high as 50 MHz, making the DAC756x, DAC816x, and DAC856x devices compatible with high-speed DSPs. On the 24th falling edge of the serialclock,thelastdatabitisclockedintotheshiftregisterandtheshiftregisterlocks.Furtherclockingdoesnot changetheshiftregisterdata. After receiving the 24th falling clock edge, the DAC756x, DAC816x, and DAC856x devices decode the three command bits, three address bits and 16 data bits to perform the required function, without waiting for a SYNC rising edge. After the 24th falling edge of SCLK is received, the SYNC line may be kept low or brought high. In either case, the minimum delay time from the 24th falling SCLK edge to the next falling SYNC edge must be met inordertobeginthenextcycleproperly;seetheSerialWriteOperationtimingdiagram(Figure1). A rising edge of SYNC before the 24-bit sequence is complete resets the SPI interface; no data transfer occurs. A new write sequence starts at the next falling edge of SYNC. To assure the lowest power consumption of the device,careshouldbetakenthatthelevelsareasclosetoeachrailaspossible. 8.5.1 SYNCInterrupt In a normal write sequence, the SYNC line stays low for at least 24 falling edges of SCLK and the addressed DAC register updates on the 24th falling edge. However, if SYNC is brought high before the 23rd falling edge, it acts as an interrupt to the write sequence; the shift register resets and the write sequence is discarded. Neither an update of the data buffer contents, DAC register contents, nor a change in the operating mode occurs (as showninFigure93). 24th Falling Edge 24thFalling Edge CLK SYNC DIN DB23 DB0 DB23 DB0 Invalid/Interrupted Write Sequence: Valid Write Sequence: Output/Mode Does Not Updateon the Falling Edge Output/Mode Updateson the Falling Edge Figure93.

The choice of the DAC8563 device takes advantage of its 16-bit resolution as well as its low typical offset error of 1 mV and gain error of 0.01% FSR. The choice of the XTR300 device is based on its strong dc performance, having a typical error of 400 µV and 0.04% FSR gain error. The XTR300 device allows a variety of both current and voltageoutputsonthesamepinwhileprovidingloadmonitoringanderrorstatuspins. The power-on reset-to-midscale feature of the DAC8563 makes the bipolar output of the XTR300 power up at 0 V or 0 A.

A recommendation for minimizing the introduction of errors into the system is to use ±0.01% tolerance RG and RSET resistors. The bypass capacitors on AV , VREF, V+ and V– should have values between 100 nF and DD 10 µF. Smaller capacitors filter fast low-energy transients, whereas the large capacitors filter the slow high- energy transients.

The port is configured in SPI master mode by setting bits 3, 5, 6, and 7 in USICTL0. The USI counter interrupt is set in USICTL1 to provide an efficient means of SPI communication with minimal software overhead. The serial clock polarity, source, and speed are controlled by settings in the USI clock control register (USICKCTL). The SYNC signal is derived from a bit-programmable pin on port 1; in this case, port line P1.4 is used. When data are to be transmitted to the DAC756x, DAC816x, or DAC856x device, P1.4 is taken low. The USI transmits data in 8-bit bytes; thus, only eight falling clock edges occur in the transmit cycle. To load data to the DAC, P1.4 is left low after the first eight bits are transmitted; then, asecondwritecycleisinitiatedtotransmitthesecondbyteofdata.P1.4istakenhighfollowingthecompletionof thethirdwritecycle.

The power applied to AV should be well-regulated and low-noise. In order to further minimize noise from the power supplies, a DD strong recommendation is to include a pair of 100-pF and 1-nF capacitors and a 0.1-μF to 1-μF bypass capacitor. The current consumption of the AV pin, the short-circuit current limit, and the load current for these DD devices are listed in the Electrical Characteristics table. Choose the power supplies for these devices to meet the aforementionedcurrentrequirements. 11 Layout 11.1 Layout Guidelines A precision analog component requires careful layout, adequate bypassing, and clean, well-regulated power supplies. The DAC756x, DAC816x, and DAC856x devices offer single-supply operation, and are often used in close proximity with digital logic, microcontrollers, microprocessors, and digital signal processors. The more digital logic present in the design and the higher the switching speed, the more difficult it is to keep digital noise from appearing at the output. As a result of the single ground pin of the DAC756x, DAC816x, and DAC856x devices, all return currents (including digital and analog return currents for the DAC) must flow through a single point. Ideally, GND would be connected directly to an analog ground plane. This plane would be separate from the ground connection for the digital components until they were connected at the power-entry point of the system. The power applied to AV should be well-regulated and low noise. Switching power supplies and dc-dc DD converters often have high-frequency glitches or spikes riding on the output voltage. In addition, digital components can create similar high-frequency spikes as their internal logic switches states. This noise can easily couple into the DAC output voltage through various paths between the power connections and analog output. As with the GND connection, AV should be connected to a power-supply plane or trace that is separate from the DD connection for digital logic until they are connected at the power-entry point. In addition, a pair of 100-pF to 1-nF capacitors and a 0.1-µF to 1-µF bypass capacitor are strongly recommended. In some situations, additional bypassing may be required, such as a 100-µF electrolytic capacitor or even a pi filter made up of inductors and capacitors – all designed essentially to provide low-pass filtering for the supply and remove the high-frequency noise. 46 SubmitDocumentationFeedback Copyright©2010–2015,TexasInstrumentsIncorporated ProductFolderLinks:DAC7562 DAC7563 DAC8162DAC8163 DAC8562 DAC8563
