DP7241 Quad Digital Potentiometer

DP7241 Quad Digital Potentiometer

The DP7241 is four Digital Potentiometers (DPs) integrated with control logic and 16 bytes of NVRAM memory. Each DP consists of a series of 63 resistive elements connected between two externally accessible end points. The tap points between each resistive element are connected to the wiper.
