Single Channel 256 Tap DP with Integrated EEPROM and I2C Control
The DP7140 is a single channel non-volatile ïWDS digital potentiometer (DP). This DP is comprised of a series of equal value resistor elements connected between two externally accessible end points. The WDS point between each resistive element can be selectively connected to the wipe output via internal CMOS switches forming a linear taper electronic potentiometer.
