ISL22512

Single Push Button Controlled Potentiometer (XDCP™)

Data Sheet

March 24, 2008

FN6679.0

Low Noise, Low Power, 16 Taps, Push

Button Controlled Potentiometer

Features

• Solid-State Non-Volatile Potentiometer

• Push Button Controlled

The Intersil ISL22512 is a three-terminal digitally-controlled

potentiometer (XDCP) implemented by a resistor array

composed of 15 resistive elements and a wiper switching

network. The ISL22512 features a push button control, a

shutdown mode, as well as an industry-leading µTQFN

package.

• Single or Auto Increment/Decrement

- Fast Mode after 1s Button Press

• AUTOSTORE of Last Wiper Position or Manual Store of

Wiper Position

The push button control has individual PU and PD inputs for

adjusting the wiper. To eliminate redundancy, the wiper

position will automatically increment or decrement if one of

these inputs is held longer than one second.

• Shutdown Mode

• 16 Wiper Tap Points

- Middle Scale Wiper Position on Power-Up

• Low Power CMOS

- V_CC= 2.7V to 5.5V

Forcing both PU and PD low for more than two seconds

activates shutdown mode. Shutdown mode disconnects the

top of the resistor chain and moves the wiper to the lowest

position, minimizing power consumption.

- Terminal Voltage, 0 to V

- Standby Current, 3µA max

• R_TOTALValue = 10kΩ

The three terminals accessing the resistor chain naturally

configure the ISL22512 as a voltage divider. A rheostat is

easily formed by floating an end terminal or connecting it to

the wiper.
