The AD5121/AD5141 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 A, B, and W 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 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 it suitablefor 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 SPI-/I2C-compatible digitalinterface that is also used to read back the wiper register andEEPROM contents.
The AD5121/AD5141 is 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.
