Description

MCP4131-103E/P 7Bit 129Step Digital Pot  This device family supports 7-bit and 8-bit resistor networks and Potentiometer and Rheostat pinouts.

Power-up/ Brown-out Control SPI Serial Interface Module & Control Logic
Wiper Lock Technology POR Wiper Setting # of Steps # of POTs Control Interface Memory Type Resistance (typical) RAB Options (k) Wiper – RW Wiper Configuration VDD Operating Range.

Floating either terminal or B allows the device to be used as a Rheostat (variable resistor). Analogue characteristics only tested from 5.5V unless otherwise noted.

MCP4131-103E/P 7Bit 129Step Digital Pot
