MCP4716A0T-E/MAY

MCP4716A0T-E/MAY is Microchip’s single-channel I2C digital potentiometer (DCP) from the MCP4716 family. It emulates a potentiometer between terminals A and B with a wiper at W, whose position is set over I2C.
Key points:
- Interface: I2C (2-wire), A0 hardware address pin to allow multiple devices on the same bus.
- Wiper resolution: typically 7-bit (0–127 steps) for W making adjustable resistance.
- End-to-end resistance: available in device variants (RAB); common values include several kilo-ohms—check the datasheet for exact options.
- Memory: supports writing to a volatile wiper register and can optionally store the setting in non-volatile memory.
- Power and temp: operates from a suitable supply (typ. 2.7–5.5 V); E suffix indicates extended temperature range; MAY indicates RoHS-compliant/date code packaging.
- Package: compact 8-pin package suitable for small PCBs.
Applications:
- Analog gain/offset adjustment in sensor interfaces and ADC references
- Calibration and tuning in instrumentation
- Replacement for mechanical pots in compact control loops and audio circuits
