The AD5124/AD5144/AD5144A potentiometers provide a nonvolatile solution for 128-/256-position adjustment applications, offering guaranteed low resistor tolerance errors of ±8% and up to ±6 mA current 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 accurate resistor matching.The high bandwidth and low total harmonic distortion (THD)ensure optimal performance for ac signals, making these devicessuitable for filter design.The low wiper resistance of only 40 Ω at the ends of the resistor array allow for pin-to-pin connection.The wiper values can be set through an SPI-/I2C-compatible digital interface that is also used to read back the wiper register andEEPROM contents.The AD5124/AD5144/AD5144A are available in a compact, 24-lead, 4 mm × 4 mm LFCSP and a 20-lead TSSOP. The partsare guaranteed to operate over the extended industrial temperaturerange of −40°C to +125°C.APPLICATIONS Portable electronics level adjustment LCD panel brightness and contrast controls Programmable filters, delays, and time constants Programmable power supplies
