DP7140 Single Channel 256 Tap DP with Integrated EEPROM and I2C Control

PublishTime：2020-08-19

The DP7140 is a single channel non-volatile 256-tap digital potentiometer (DP). This DP 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 DP7140 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 I²C interface. On power up，the wiper position is reset to the most recent value stored in the non-volatile memory register (IVR).

The DP7140 is available in an Pb free, RoHS compliant 8-lead MS OP package, and operates over the industrial temperature range of -40°C to +85°C.
