 Digital Potentiometer (POT), 256-Tap, with I2CInterface and Integrated EEPROM

制造商:ON

中文数据手册

产品信息

The CAT5140 is a single channel non-volatile 256-tap digital POT. This digital POT is comprised of a series of equal value resistor elements connected between two externally accessible end points. The tap points between each resistive element can be selectively connected to the wiper output via internal CMOS switches forming a linear taper electronic potentiometer.
The CAT5140 contains a volatile wiper register (WR) and an 8-bit non-volatile EEPROM for wiper position and 5 additional non-volatile registers for general purpose data storage. Programming of the registers is controlled via I
C interface. On power up, the wiper position is reset to the most recent value stored in the non-volatile memory register (IVR).
The CAT5140 operates over the industrial temperature range of -40°C to +85°C.
