Single, Low Voltage Digitally Controlled Potentiometer  
(XDCP™)  
ISL23415  
The ISL23415 is a volatile, low voltage, low noise, low power,  
SPI™ bus, 256 taps, single digitally controlled potentiometer  
(DCP), which integrates DCP core, wiper switches and control  
logic on a monolithic CMOS integrated circuit.  
Features  
• 256 resistor taps  
• SPI serial interface  
- No additional level translator for low bus supply  
- Daisy Chaining of multiple DCP  
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  
SPI bus interface. The potentiometer has an associated  
volatile Wiper Register (WR) that can be directly written to and  
read by the user. The contents of the WR controls the position  
of the wiper. When powered on, the ISL23415’s wiper will  
always commence at mid-scale (128 tap position).  
• Power supply  
- V = 1.7V to 5.5V analog power supply  
CC  
- V  
LOGIC  
= 1.2V to 5.5V SPI bus/logic power supply  
• Wiper resistance: 70Ω typical @ V = 3.3V  
CC  
• Shutdown Mode - forces the DCP into an end-to-end open  
circuit and RW is shorted to RL internally  
• Power-on preset to mid-scale (128 tap position)  
• Shutdown and standby current <2.8µA max  
The low voltage, low power consumption, and small package  
of the ISL23415 make it an ideal choice for use in battery  
operated equipment. In addition, the ISL23415 has a V  
LOGIC  
• DCP terminal voltage from 0V to V  
CC  
pin allowing down to 1.2V bus operation, independent from the  
value. This allows for low logic levels to be connected  
• 10kΩ, 50kΩ or 100kΩ total resistance  
• Extended industrial temperature range: -40°C to +125°C  
• 10 Ld MSOP or 10 Ld µTQFN packages  
• Pb-free (RoHS compliant)  
V
CC  
directly to the ISL23415 without passing through a voltage  
level shifter.  
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.  
Applications  
• Power supply margining  
• RF power amplifier bias compensation  
• LCD bias compensation  
• Gain adjustment in battery powered instruments  
• Portable medical equipment calibration
