ISL90728 Datasheet Digitally Controlled Potentiometer

Manufacturer: Renesas

Overview: 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. Between each element and at either end are tap points accessible to the wiper terminal. The position of the wiper element is controlled by the SDA and SCL inputs.

This datasheet includes multiple variants, all published together in a single manufacturer document.
