Low Noise, Low Power, 32 Taps, Push

Button Controlled Potentiometer

The Intersil ISL23511 is a three-terminal digitally-controlled

potentiometer (XDCP) implemented by a resistor array

composed of 31 resistive elements and a wiper switching

network. The ISL23511 features a push button control, a

shutdown mode, as well as an industry-leading µTQFN

package.

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 1s.

Forcing both PU and PD low for more than 2s activates

shutdown mode. Shutdown mode disconnects the top of the

resistor chain and moves the wiper to the lowest position,

minimizing power consumption.

The three terminals accessing the resistor chain naturally

configure the ISL23511 as a voltage divider. A rheostat is

easily formed by floating an end terminal or connecting it to

the wiper.
