Low Noise, Low Power, 16 Taps, Push
Button Controlled Potentiometer
The Intersil ISL23512 is a three-terminal digitally-controlled
potentiometer (XDCP) implemented by a resistor array
composed of 15 resistive elements and a wiper switching
network. The ISL23512 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 ISL23512 as a voltage divider. A rheostat is
easily formed by floating an end terminal or connecting it to
the wiper.

NOTES:
1. These Intersil Pb-free plastic packaged products employ special Pb-free material sets; molding compounds/die attach materials and NiPdAu
plate - e4 termination finish, which is RoHS compliant and compatible with both SnPb and Pb-free soldering operations. Intersil Pb-free products
are MSL classified at Pb-free peak reflow temperatures that meet or exceed the Pb-free requirements of IPC/JEDEC J STD-020.
2. Please refer to TB347 for details on reel specifications.
