ISL23511

DATASHEET ISL23511 Single Push Button Controlled Potentiometer (XDCP™) Low Noise, Low Power, 32 Taps, Push Button Controlled Potentiometer FN6588 Rev 2.00 September 9, 2015 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 i...
