Description

The Intersil X93154 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 X93154 potentiometer is implemented by a resistor array composed of 31 resistive elements and a wiper switching network. The position of the wiper element is controlled by the CS, U/D, and INC inputs. The position of the wiper can be stored in nonvolatile memory and then be recalled upon a subsequent power-up operation.

The X93154 is connected as a two-terminal variable resistor and can be used in a wide variety of applications including:
- Bias and Gain Control
- LCD Contrast Adjustment
