X9313, Digitally Controlled Potentiometer

RH/VH and RL/VL The high (RH/VH) and low (RL/VL) terminals of the X9313 are equivalent to the fixed terminals of a mechanical potentiometer.

The terminology of RL/VL and RH/VH references the relative position of the terminal in relation to wiper movement direction selected by the U/D input and not

DATASHEET X9313 Digitally Controlled Potentiometer (XDCP™) Linear, 32 Taps, 3 Wire Interface, Terminal Voltages ± VCC FN8177 Rev 7.00 October 7, 2015 The Intersil X9313 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 3-wire interface.

The potentiometer is implemented by a resistor array composed of 31 resistive elements and a wiper switching network.
