The Intersil X9317 is a digitally controlled potentiometer (XDCP) with low noise, low power, and 100 tap points. It can be used as a three-terminal potentiometer for voltage control or as a two-terminal variable resistor for current control.
The Intersil X9317 is a digitally controlled potentiometer (XDCP) that consists of a resistor array, wiper switches, a control section, and nonvolatile memory. The device features a 3-wire serial up/down interface to control the wiper position, which can be stored in memory and recalled upon power-up. It is implemented with 99 resistive elements and provides 100 accessible tap points.
