MCP4021T-103E/SN

The MCP4021 devices are non--volatile, 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 WiperLock technology, which allows application-specific calibration settings to be secured in the EEPROM without requiring the use of an additional write-protect pin.
