Rev 2.00  
September 23, 2015  
Dual, 128-Tap, Low Voltage Digitally Controlled Potentiometer (XDCP™)  
The ISL23428 is a volatile, low voltage, low noise, low power,  
Features  
128-tap, dual digitally controlled potentiometer (DCP) with an  
SPI Bus™ interface. It integrates two DCP cores, wiper switches  
and control logic on a monolithic CMOS integrated circuit.  
• Two potentiometers per package  
• 128 resistor taps  
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  
SPI 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).  
• 10k 50kor 100ktotal resistance  
• SPI serial interface  
- No additional level translator for low bus supply  
- Daisy Chaining of multiple DCPs  
• Power supply  
- V = 1.7V to 5.5V analog power supply

- V  
LOGIC  
= 1.2V to 5.5V SPI bus/logic power supply  
The low voltage, low power consumption, and small package  
of the ISL23428 make it an ideal choice for use in battery  
• Maximum supply current without serial bus activity  
(standby)  
operated equipment. In addition, the ISL23428 has a V  
LOGIC  
pin allowing down to 1.2V bus operation, independent from the  
value. This allows for low logic levels to be connected

directly to the ISL23428 without passing through a voltage  
level shifter.  
• Shutdown Mode  
- Forces the DCP into an end-to-end open circuit and RWi is  
connected to RLi internally  
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.  
- Reduces power consumption by disconnecting the DCP  
resistor from the circuit  
• Wiper resistance: 70typical @ V = 3.3V  
Applications  
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)  
• Power supply margining  
• Trimming sensor circuits  
• Gain adjustment in battery powered instruments  
• RF power amplifier bias compensation
