MCP4261-103E/P Datasheet PDF - Microchip

The MCP4261-103E/P is a 8-bit single SPI Digital Potentiometer with non-volatile memory. This device offers a wide range of product offerings using an SPI interface. WiperLock Technology allows application-specific calibration settings to be secured in the EEPROM. The MCP42XX family is available with end-to-end resistor values of 10kR. This device offer WiperLock™ technology which allows the user unlimited reprogramming and locking of the wiper setting. It is useful for equipment that requires factory trimming or recalibration.
