Single, 128-Tap, Low Voltage Digitally Controlled

Potentiometer (XDCP™)

ISL23418

The ISL23418 is a volatile, low voltage, low noise, low power,

SPI™ bus, 128 taps, single digitally controlled potentiometer

(DCP), which integrates DCP core, wiper switches, and control

logic on a monolithic CMOS integrated circuit.

Features

• 128 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 wiper is 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 ISL23418 wiper always

commences at mid-scale (64-tap position).

• Wiper Resistance: 70Ω Typical @ V = 3.3V

• Shutdown Mode: Forces DCP into End-to-end Open Circuit;

RW Shorted to RL Internally

• Power-on Preset to Mid-scale (64-tap Position)

• Shutdown and Standby Current <2.8µA Max

• Power Supply

- V = 1.7V to 5.5V Analog Power Supply

The low voltage, low power consumption, and small package

size of the ISL23418 make it an ideal choice for use in battery

operated equipment. The ISL23418 has a V

down to 1.2V bus operation, independent from the V value.

pin allowing

LOGIC

• DCP Terminal Voltage from 0V to V

• 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)

This allows for low logic levels to be connected directly to the

ISL23418 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
