Terminal Voltage ±3V or ±5V, 128 Taps I

Serial Interface

The Intersil ISL23711 is a digitally controlled potentiometer

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

switches, and a control section. The wiper position is

controlled by an I

The potentiometer is implemented by a resistor array

composed of 127 resistive elements and a wiper switching

network. The wiper terminal can be connected to either end

of the resistor array or at any one of the Tap Positions in

between, providing 128 steps of resolution between R

assigned to the volatile Wiper Register (WR). The WR can

be directly written to and read from using standard I

interface protocol. The device is available in either a 10kΩ or

50kΩ version.

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

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

PART NUMBER

. The “position” of the wiper is determined by the value

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.
