Rev 8.00  
May 10, 2012  
The Intersil ISL90727 and ISL90728 are digitally controlled  
potentiometers (XDCP™). Each device consists of a resistor  
Features  
• Volatile Solid-State Potentiometer  
array, wiper switches, and a control section. The wiper

position is controlled by an I C Bus™.  
• I C Serial Bus Interface  
• DCP Terminal Voltage, 2.7V to 5.5V  
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.  
• Low Tempco  
- Rheostat - 45 ppm/°C Typical  
- Divider - 15 ppm/°C Typical  
• 128 Wiper Tap Points  
- Wiper Resistance 70Typ at V

1. Please refer to TB347 for details on reel specifications.  
2. These Intersil Pb-free plastic packaged products employ special Pb-free material sets, molding compounds/die attach materials, and 100% matte tin  
plate plus anneal (e3 termination finish, which is RoHS compliant and compatible with both SnPb and Pb-free soldering operations). Intersil Pb-free  
products are MSL classified at Pb-free peak reflow temperatures that meet or exceed the Pb-free requirements of IPC/JEDEC J STD-020.  
3. For Moisture Sensitivity Level (MSL), please see device information page for ISL90727, ISL90728. For more information on MSL please see  
Tech Brief TB363.
