説明
Support is limited to customers who have already adopted these products.
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 points accessible to the wiper terminal. The position of the wiper element is controlled by the SDA and SCL inputs.
