New digitally programmable potentiometer available from Catalyst Semiconductor
Report dead link
Reference: 25997
Catalyst Semiconductor has announced the availability of its popular CAT5114 Digitally Programmable Potentiometer in an 8-lead 2 x 2.5mm TDFN package, making it one of the smallest non-volatile digital potentiometers available. 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 small 2 x 2.5 TDFN package. The CAT5114 is also functionally equivalent to Intersil's X93154 50kΩ digital potentiometer, with additional 10kΩ and 100 kΩ 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 include a 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: 10kΩ, 50kΩ, 100kΩ; non-volatile EEPROM wiper storage; increment up/down serial interface; single supply operation: 2.5V - 6V; and low standby current
Samples are available now. Projected lead-time for production quantities is currently 6 to 8 weeks ARO.
