ISL90726, Digitally Controlled Potentiometer

DATASHEET ISL90726 Single Volatile 128-Tap XDCP™ Digitally Controlled Potentiometer (XDCP) FN8244 Rev 4.00 August 26, 2008 The Intersil ISL90726 is a digitally controlled potentiometer (XDCP).

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

The wiper position is controlled by an I2C interface.

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

Between each element and at either end are tap poin
