Digitally Controlled Potentiometer  
(XDCP™)  
Features  
• Volatile Solid-State Potentiometer  
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

• DCP Terminal Voltage, 2.7V to 5.5V

position is controlled by an I C Bus™.  
• Low Tempco  
- Rheostat - 45 ppm/°C Typical  
- Divider - 15 ppm/°C Typical  
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.
