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 Ω 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.
