Digitally programmable potentiometer comes in 2 x 2.5mm TDFN package

Catalyst Semiconductor, Inc. has announced the availability of its popular CAT5114 Digitally Programmable Potentiometer™ in an 8-lead 2 x 2.5mm TDFN package, making it the world’s smallest non-volatile digital potentiometer. This tiny form factor helps designers further compress board space in today’s ever-shrinking portable products which currently use digital potentiometers in larger packages. The CAT5114 in 2 x 2.5mm TDFN can also be used to replace mechanical potentiometers and trimpots in applications including LCD screen adjustment; tamper-proof product calibration; contrast, brightness and volume control; gain adjustment; motor control and feedback systems.

The CAT5114 digital potentiometer is a pin-for-pin replacement for Intersil’s X9315, but offers the added choice of the very small 2 x 2.5 TDFN package. The CAT5114 is also functionally equivalent to Intersil’s X93154 50kOhm digital potentiometer, with additional 10kOhm and 100 kOhm end-to-end resistance values and a wider supply voltage range (2.5V to 6V).

The tiny CAT5114 is a 32-tap digital potentiometer featuring a user-friendly up/down control interface and non-volatile memory, which retains the wiper setting on system power-down and reinstates the setting when power is returned. The wiper can be adjusted to test new system values without affecting the stored setting.

Product Features
– 32-position linear taper potentiometer
– Packaging: 2 x 2.5mm TDFN 8-lead
(TDFN 2 x 3mm, TSSOP, SOIC, MSOP, PDIP also available)
– Resistance values: 10kOhm, 50kOhm, 100kOhm
– Non-volatile EEPROM wiper storage
