The AD5123/AD5143 potentiometers provide a nonvolatilesolution for 128-/256-position adjustment applications, offeringguaranteed low resistor tolerance errors of ?8% and up to ?6 mAcurrent density in the Ax, Bx, and Wx pins.The low resistor tolerance and low nominal temperature coefficientsimplify open-loop applications as well as applications requiringtolerance matching.The linear gain setting mode allows independent programmingof the resistance between the digital potentiometer terminals,through the RAW and RWB string resistors, allowing very accurateresistor matching.The high bandwidth and low total harmonic distortion (THD)ensure optimal performance for ac signals, making the devicessuitable for filter design.The low wiper resistance of only 40 ? at the ends of the resistorarray allows for pin to pin connection.The wiper values can be set through an I2C-compatible digitalinterface that also reads back the wiper register and EEPROMcontents.The AD5123/AD5143 are available in a compact, 16-lead, 3 mm ?3 mm LFCSP. The devices are guaranteed to operate over theextended industrial temperature range of ?40?C to +125?C.

The AD5160 provides a compact 2.9 mm ? 3 mm packaged solution for 256-position adjustment applications. These devices perform the same electronic adjustment function as mechanical potentiometers1 or variable resistors but with enhanced resolution, solid-state reliability, and superior low temperature coefficient performance.The wiper settings are controllable through an SPI-compatible digital interface. The resistance between the wiper and either end point of the fixed resistor varies linearly with respect to the digital code transferred into the RDAC latch.Operating from a 2.7 V to 5.5 V power supply and consuming less than 5 ?A allows for usage in portable battery-operated applications.

The AD5204/AD5206 provide 4-/6-channel, 256-position digitally controlled variable resistor (VR) devices. These devices perform the same electronic adjustment function as a potentiometer or variable resistor. Each channel of the AD5204/AD5206 contains a fixed resistor with a wiper contact that taps the fixed resistor value at a point determined by a digital code loaded into the SPI-compatible serial-input register. The resistance between the wiper and either endpoint of the fixed resistor varies linearly with respect to the digital code transferred into the VR latch. The variable resistor offers a completely programmable value of resistance between the A terminal and the wiper or the B terminal and the wiper. The fixed A-to-B terminal resistance of 10 k?, 50 k?, or 100 k? has a nominal temperature coefficient of 700 ppm/?C.Each VR has its own VR latch that holds its programmed resistance value. These VR latches are updated from an internal serial-to-parallel shift register that is loaded from a standard 3-wire serial-input digital interface. Eleven data bits make up the data-word clocked into the serial input register. The first three bits are decoded to determine which VR latch is loaded with the last eight bits of the data-word when the CS strobe is returned to logic high. A serial data output pin at the opposite end of the serial register (AD5204 only) allows simple daisy chaining in multiple VR applications without requiring additional external decoding logic.An optional reset (PR) pin forces all the AD5204 wipers to the midscale position by loading 0x80 into the VR latch.The AD5204/AD5206 are available in the 24-lead surface-mount SOIC and TSSOP packages. The AD5204 is also available in a 32-lead, 5 mm ? 5 mm LFCSP package. All parts are guaranteed to operate over the extended industrial temperature range of ?40?C to +85?C.

Their on-chip output amplifiers allow rail-to-rail output swing to be achieved with a slew rate of 0.7 V/?s. A 3-wire serial interface is used; it operates at clock rates up to 30 MHz and is compatible with standard SPI, QSPI, MICROWIRE, and DSP interface standards.The references for the four DACs are derived from one reference pin. The outputs of all DACs can be updated simultaneously using the software LDAC function. The parts incorporate a power-on reset circuit, and ensure that the DAC outputs power up to 0 V and remains there until a valid write takes place to the device. The parts contain a power-down feature that reduces the current consumption of the device to 200 nA @ 5 V (80 nA @ 3 V).The low power consumption of these parts in normal operation makes them ideally suited to portable battery-operated equipment. The power consumption is 3 mW at 5 V, 1.5 mW at 3 V, reducing to 1 ?W in power-down mode.Applications Portable battery-powered instruments Digital gain and offset adjustment Programmable voltage and current sources Programmable attenuators Industrial process controls
