CAT5116

Log-Taper, 100-Tap Digitally Programmable Potentiometer (DPP™)

FEATURES

DESCRIPTION

100-position, log-taper potentiometer

Non-volatile EEPROM wiper storage

10nA ultra-low standby current

Single-supply operation: 2.5V – 5.5V

Increment Up/Down serial interface

Resistance value: 32kΩ

The CAT5116 is a log-taper single digitally program-

mable potentiometer (DPP™) designed as a electro-

nic replacement for mechanical potentiometers.

Ideal for automated adjustments on high volume

production lines, DPP ICs are well suited for applica-

tions where equipment requiring periodic adjustment

is either difficult to access or located in a hazardous or

remote environment.

Available in 8-pin MSOP, TSSOP, SOIC and DIP

packages

The CAT5116 contains a 100-tap series resistor array

connected between two terminals R_Hand R_L. An

up/down counter and decoder that are controlled by

three input pins, determines which tap is connected to

the wiper, R_W.

APPLICATIONS

Automated product calibration

Remote control adjustments

Offset, gain and zero control

Audio volume control

The wiper setting, stored in nonvolatile memory, is not

lost when the device is powered down and is

automatically reinstated when power is returned. The

wiper can be adjusted to test new system values

without effecting the stored setting.

Sensor adjustment

Motor controls and feedback systems

Programmable analog functions

Wiper-control of the CAT5116 is accomplished with

¯¯

¯¯¯

three input control pins, CS, U/D, and INC. The INC

input increments the wiper in the direction which is

¯¯

determined by the logic state of the U/D input. The CS

input is used to select the device and also store the

wiper position prior to power down.

For Ordering Information details, see page 11.

The digitally programmable potentiometer can be used

as a three-terminal resistive divider or as a two-terminal

variable resistor.
