X9C303 Datasheet (Intersil Corporation) - Logarithmic Digitally Controlled Potentiometer

X9C303, Logarithmic Digitally Controlled Potentiometer

The Intersil X9C303 is a digitally controlled potentiometer (XDCP).

The device consists of a resistor array, wiper switches, a control section, and nonvolatile memory.

The wiper position is controlled by a three-wire interface.

The resistor array is composed of 99 resistive elements.
