Qualification data available on request APPLICATIONS Missiles and munitions Avionics and unmanned systems Programmable filters, delays, and time constants Programmable power supplies GENERAL DESCRIPTION The AD5144-EP potentiometer provides a nonvolatile solution The low wiper resistance of 40 at the ends of the resistor array for 256-position adjustment applications, offering guaranteed low allow for pin-to-pin connection. resistor tolerance errors of 8% and up to 6 mA current density The wiper values can be set through a serial peripheral interface in the Ax, Bx, and Wx pins. (SPI) digital interface that is also used to read back the wiper The low resistor tolerance and low nominal temperature register and electronically erasable programmable read-only coefficient simplify open-loop applications as well as memory (EEPROM) contents. applications requiring tolerance matching. The AD5144-EP is available in a 20-lead TSSOP. The device is The linear gain setting mode allows independent programming guaranteed to operate over the 55C to +125C temperature of the resistance between the digital potentiometer terminals, range. through the Terminal A to Terminal W (R ) and the Terminal W AW Additional application and technical information can be found to Terminal B (RWB) string resistors, allowing accurate resistor in the AD5144 data sheet. matching. The high bandwidth and low total harmonic distortion (THD) ensure optimal performance for ac signals, making this device suitable for filter design. Rev.
