MCP4021 Datasheet (Microchip Technology)

MCP4021, Low-Cost NV Digital POT

The MCP4021/2/3/4 devices are nonvolatile, 6-bit digital potentiometers that can be configured as either a potentiometer or rheostat.

The wiper setting is controlled through a simple Up/Down (U/D) serial interface.

These device’s implement Microchip’s WiperLock™ technology, which allows application-
