ISL23511

Low Noise, Low Power, 32 Taps, Push Button Controlled Potentiometer

Product Status: Mass Production

OVERVIEW

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 one second.

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.

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.
