CAT5140 digital potentiometer
256-Tap Digital Potentiometer with I²C Interface and Integrated EEPROM

CAT5140: Digitally Programmable Potentiometer (DPP™) with 50 kΩ and 100 kΩ end-to-end resistance

Phoenix, Ariz. – May 14, 2009 - ON Semiconductor (Nasdaq: ONNN), a leading global supplier of high performance, energy efficient, silicon solutions has added a new 256-tap, single-channel linear-taper device to its extensive family of Digitally Programmable Potentiometers (DPP™). The CAT5140 digital potentiometer is a low-noise, reliable and space-saving alternative to DACs and mechanical potentiometers. It features an on-chip, 8-bit, non-volatile EEPROM memory, which allows designers to calibrate once and retain the wiper setting in memory on power-up. The new DPP™ also provides five additional non-volatile registers for general purpose data storage, as well as a volatile wiper register for applications requiring temporary storage.
