ISL22511
Single Push Button Controlled Potentiometer (XDCP™)
Low Noise, Low Power, 32 Taps, Push
Button Controlled Potentiometer
The Intersil 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, as well as 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 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 ISL22511 as a voltage divider. A rheostat is
easily formed by floating an end terminal or connecting it to
the wiper.
