ISL22511 - Single Push-Button Controlled Potentiometer

Description

Falling-edge triggered input with internal pull-up.

Toggle PU to move the wiper close to the RH terminal.

The debounced PU input increments the wiper position.

Features

  • a push-button control, a Shutdown mode, and an industry-leading UTQFN package. The push-button control has individual PU and PD inputs for adjusting the wiper. To eliminate redundancy, the wiper position automatically increments or decrements 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 to minimize power consump.

Datasheet ISL22511 Low Noise, Low Power, 32 Taps, Up/Down, Single Push-Button Controlled Potentiometer (XDCP™) The ISL22511 is a three-terminal digitally-controlled potentiometer (XDCP) implemented by a resistor array composed of 31 resistive elements and a wiper switching network. The ISL22511 features a push-button control, a Shutdown mode, and an industry-leading UTQFN package. The push-button control has individual PU and PD inputs for adjusting the wiper. To eliminate redundancy, the wiper position automatically increments or decrements 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.
