MCP4641-103E/ST

TheMCP4641 device offer a wide range of product offerings using an I2C interface. This family of devices support 7-bit and 8-bit resistor networks, Non-Volatile memory configurations, and Potentiometer and Rheostat pinouts. WiperLock Technology allows application-specific calibration settings to be secured in the EEPROM.
