Precision Single Digitally Controlled Potentiometer (XDCP™)  
Data Sheet

FN6912.1

Low Noise, Low Power, I C Bus, 128 Taps  
Features  
The digitally controlled potentiometer is implemented with a  
combination of resistor elements and CMOS switches. The  
position of the wiper is controlled by the user through the I C  
• Precision Digitally Controlled Potentiometer  
- 99% Typical Accuracy Of Resistance Over Operational  
Conditions

bus interface. The potentiometer has an associated volatile  
Wiper Register (WR) and a non-volatile Initial Value Register  
(IVR) that can be directly written to and read by the user. The  
contents of the WR control the position of the wiper. At  
power up, the device recalls the contents of the DCP’s IVR  
to the WR.  
- Zero-Compensated Wiper Resistance  
• Integrated Digitally Controlled Potentiometer  
- 128-Tap Positions

- I C Serial Interface  
- Pin Selectable Slave Address  
- 10kΩ, 50kΩ and 100kΩTotal Resistance  
- Monotonic Over-Temperature  
The highly precise ISL22317 features a low end-to-end  
temperature coefficient of TC_Ref ±10ppm/°C and precise  
resistance selection. It maintains less than ±1% typical  
variance from the ideal resistance at each wiper position  
providing 99% accuracy of selected resistance value. This  
highly accurate DCP eliminates the need for complex  
algorithms to guarantee precision. The ISL22317 allows the  
user to dial in an accurate resistance and the EEPROM  
memory stores the set value for life, or until changed by the  
user.  
- Non-Volatile EEPROM Storage of Wiper Position  
- 0 to VCC Terminal Voltage  
• Single 2.7V to 5.5V Supply  
• High Reliability  
- 50 Years Retention @ ≤ +55°C  
- 15 Years Retention @ +125°C  
- 1,000,000 Cycles Endurance  
• 3mmx3mm Thin DFN Package – 0.75mm Max Thickness,  
0.65mm Pitch  
An external 0.5% or better reference resistor must be  
attached to the ISL22317. The ISL22317 will mirror both the  
precise resistance and temperature coefficient of the  
external resistor.  
• Pb-Free (RoHS Compliant)  
Applications  
The DCP can be used as a three-terminal potentiometer or  
as a two-terminal variable resistor in a wide variety of  
applications including control, parameter adjustments, and  
signal processing.
