ISL22323  
Dual Digitally Controlled Potentiometer (XDCP)  
Low Noise, Low Power, I C Bus, 256 Taps

The ISL22323 integrates two digitally controlled  
potentiometers (DCP), control logic and non-volatile memory  
on a monolithic CMOS integrated circuit.  
Features  
• Two potentiometers in one package  
• 256 resistor taps  
The digitally controlled potentiometer is implemented with a  
combination of resistor elements and CMOS switches. The  
position of the wipers are controlled by the user through the  
2
• I C serial interface  
- Three address pins, up to eight devices per bus  
• Non-volatile EEPROM storage of wiper position  
• 13 General Purpose non-volatile registers

I C bus interface. The potentiometer has an associated  
volatile Wiper Register (WRi) and a non-volatile Initial Value  
Register (IVRi) that can be directly written to and read by the  
user. The contents of the WRi control the position of the  
corresponding wiper. At power up the device recalls the  
contents of the DCP’s IVRi to the correspondent WRi.  
• High reliability  
- Endurance: 1,000,000 data changes per bit per register  
- Register data retention: 50 years @ T +55°C  
The ISL22323 also has 13 general purpose non-volatile  
registers that can be used as storage of lookup table for  
multiple wiper position or any other valuable information.  
• Wiper resistance: 70typical @ 1mA  
• Standby current <4µA max  
• Shut-down current <4µA max  
• Dual power supply  
The ISL22323 features a dual supply, that is beneficial for  
applications requiring a bipolar range for DCP terminals  
between V- and VCC.  
- V  
CC  
= 2.25V to 5.5V  
- V- = -2.25V to -5.5V  
Each DCP can be used as three-terminal potentiometers or  
as two-terminal variable resistors in a wide variety of  
applications including control, parameter adjustments, and  
signal processing.  
• 10k 50kor 100ktotal resistance  
• Extended industrial temperature range: -40 to +125°C  
• 14 Ld TSSOP or 16 Ld QFN  
• Pb-free (RoHS compliant)
