Dual, 128-Tap, Low Voltage Digitally Controlled  
Potentiometer (XDCP™)  
ISL23328  
Features  
• Two potentiometers per package  
• 128 resistor taps  
The ISL23328 is a volatile, low voltage, low noise, low power,  
128-Tap, dual digitally controlled potentiometer (DCP) with an  
2
I C Bus™ interface. It integrates two DCP cores, wiper switches  
• 10k, 50kor 100ktotal resistance  
and control logic on a monolithic CMOS integrated circuit.  
2
• I C serial interface  
Each 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 I C  
- No additional level translator for low bus supply  
- Three address pins allow up to eight devices per bus  
2
bus interface. Each potentiometer has an associated volatile  
Wiper Register (WRi, i = 0, 1) that can be directly written to and  
read by the user. The contents of the WRi controls the position  
of the wiper. When powered on, the wiper of each DCP will  
always commence at mid-scale (64 tap position).  
• Power supply

LOGIC

• Maximum supply current without serial bus activity  
(standby)  
The low voltage, low power consumption, and small package  
of the ISL23328 make it an ideal choice for use in battery

operated equipment. In addition, the ISL23328 has a V

pin allowing down to 1.2V bus operation, independent from the

value. This allows for low logic levels to be connected  
CC  
- Forces the DCP into an end-to-end open circuit and RWi is  
connected to RLi internally  
directly to the ISL23328 without passing through a voltage  
level shifter.  
- Reduces power consumption by disconnecting the DCP  
resistor from the circuit  
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.  
• Wiper resistance: 70typical @ V = 3.3V  
CC  
• Power-on preset to mid-scale (64 tap position)  
• Extended industrial temperature range: -40°C to +125°C  
• 14 Ld TSSOP or 16 Ld UTQFN packages  
• Pb-free (RoHS Compliant)  
Applications  
• Power supply margining  
• Trimming sensor circuits  
• Gain adjustment in battery powered instruments  
• RF power amplifier bias compensation
