 Description |
|
|
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. |
