space saving 2 x 2.5mm TDFN packages

DESCRIPTION

The CAT5114 is a single digitally programmable

potentiometer (DPP™) designed as a electronic

replacement for mechanical potentiometers and trim

pots. Ideal for automated adjustments on high volume

production lines, they are also well suited for

applications where equipment requiring periodic

adjustment is either difficult to access or located in a

hazardous or remote environment.

The CAT5114 contains a 32-tap series resistor array

connected between two terminals R

and R

. An up/

down counter and decoder that are controlled by three

input pins, determines which tap is connected to the

wiper, R

. 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 affecting the stored setting.

Wiper-control of the CAT5114 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.

The digitally programmable potentiometer can be

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

terminal variable resistor. DPPs bring variability and

programmability to a wide variety of applications

including control, parameter adjustments, and signal

processing.

APPLICATIONS

Automated product calibration

Remote control adjustments

Offset, gain and zero control

Tamper-proof calibrations

Contrast, brightness and volume controls

Motor controls and feedback systems

Programmable analog functions
