The MAX5394 single, 256-tap volaTIle, low-voltagelinear taper digital potenTIometer offers three end-toendresistance values of 10kΩ, 50kΩ, and 100kΩ.PotenTIometer terminals are independent of supply for
voltages up to 5.25V with single-supply operaTIon from1.7V to 5.5V (charge pump enabled). User-controlledshutdown modes allow the H, W, or L terminal to beopened with the wiper position set to zero-code, midcode,full-code, or the value contained in the wiperregister. Ultra-low-quiescent supply current (< 1μA) canbe achieved for supply voltages between 2.6V and 5.5Vby disabling the internal charge pump and not allowingpotentiometer terminals to exceed the supply voltage bymore than 0.3V. The MAX5394 provides a low 50ppm/°Cend-to-end temperature coefficient and features a SPIserial interface.
