ISL90727, Digitally Controlled Potentiometer

DATASHEET ISL90727, ISL90728 Single Volatile 128-Tap XDCP™ Digitally Controlled Potentiometer (XDCP) FN8247 Rev 8.00 May 10, 2012 The Intersil ISL90727 and ISL90728 are digitally controlled potentiometers (XDCP™).

Each device consists of a resistor array, wiper switches, and a control section.

The wiper position is controlled by an I2C Bus™.

The potentiometer is implemented by a resistor array composed of 127 resistive elements and a wiper switching network.
