ISL95710

Digitally Controlled Potentiometer (XDCP™)

Terminal Voltage ±3V or ±5V, 128 Taps

Up/Down Interface

The Intersil ISL95710 is a digitally controlled potentiometer

(XDCP). The device consists of a resistor array, wiper

switches, a control section, and nonvolatile memory. The

wiper position is controlled by a Up/Down interface.

The potentiometer is implemented by a resistor array

composed of 127 resistive elements and a wiper switching

network. Between each element and at either end are tap

points accessible to the wiper terminal. The position of the

wiper element is controlled by the CS, U/D, and INC inputs.

The position of the wiper can be stored in nonvolatile

memory and then be recalled upon a subsequent power-up

operation.

The device can be used as a three-terminal potentiometer or

as a two-terminal variable resistor in a wide variety of

applications including:

• Industrial and automotive control

• Parameter and bias adjustments

• Amplifier bias and control

NOTES:

1. Add “-T” suffix for tape and reel.

2. Intersil Pb-free plus anneal products employ special Pb-free

material sets; molding compounds/die attach materials and

100% matte tin plate termination finish, which are 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.
