ISL95711

Digitally Controlled Potentiometer (XDCP™)

Terminal Voltage ±2.7V or ±5V, 128 Taps

The Intersil ISL95711 is a digitally controlled potentiometer

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

switches, a control section, and nonvolatile memory. The

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

assigned to the volatile Wiper Register (WR). This register

has an associated non-volatile Initial Value Register (IVR).

The value stored in the IVR will be written into the WR at

power-up, allowing wiper position recall after power

interruption. The WR and the IVR can be directly written to

device is available in either a 10k

Ω 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

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.
