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

position is controlled by an I C interface.  
• 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.  
• 128 Wiper Tap Points  
- Wiper resistance 70Ω typ at V  
= 3.3V  
CC  
• Low Power CMOS  
The device can be used in a wide variety of applications  
including:  
- Active current, 200µA max  
- Standby current, 500nA max  
• Mechanical potentiometer replacement  
• Available R  
TOTAL  
Values = 50kΩ, 10kΩ  
• Transducer adjustment of pressure, temperature, position,  
chemical, and optical sensors  
• Power on Preset to Midscale  
• Direct Replacement for AD5247  
• RF amplifier biasing  
• Packaging  
- 6 Ld SC-70  
• LCD brightness and contrast adjustment  
• Gain control and offset adjustment  
• Pb-Free Plus Anneal Available (RoHS Compliant)
