Description

The MCP4716A0T-E/MAY is Microchip’s single-channel digital potentiometer (DPot) in an 8‑pin package. It provides a programmable resistance between its end terminals A and B, controlled by the Wiper (W) via a serial SPI‑compatible interface. Use it to trim analog signals, calibrate sensors, set gains, or tune LED drivers without external DACs or resistors. The device has a fixed end‑to‑end resistance per part and a defined number of wiper steps (resolution depends on variant). The suffixes A0T-E/MAY identify the part revision, packaging, and extended temperature/lot code; exact values (RAB, voltage range, memory behavior) are in the datasheet. Typical pins: CS, SCK, SI/SO, VDD, VSS, A, B, W. Operation: write to the wiper register to move W and hence alter the A–B resistance seen in your circuit. For precise specs, refer to the MCP4716 data sheet.

Features

Key features of MCP4716A0T-E/MAY (datasheet gives exact values per variant; verify for your part):
- Single-channel I2C digital potentiometer
- 8-bit wiper resolution (0–255 steps)
- End-to-end resistance fixed per device variant (RAB options available)
- Nonvolatile memory to store/recall wiper position after power-up
- Volatile wiper register plus NV memory interface (write, save, recall)
- Operating voltage typically 2.7 V to 5.5 V
- Low current consumption; suitable for battery-powered apps
- Temperature range commonly -40°C to +125°C
- 8-pin package (SOP/MSOP) with Tape-and-Reel option (-T)
- I2C addressing via A0 pin (part code indicates address variant)
Note: Please consult the official datasheet for exact electrical specs, RAB values, and pinout for the A0/E/MAY suffix variant.

Pinout

8-pin package (SOIC/DIP-8). It is a digital potentiometer with three external terminals A, B (the end-to-end ends) and W (the wiper). It is controlled by a 3-wire serial interface (CS, SCK, SI) and powered by VDD and VSS. The A–B ends form the potentiometer, and the W pin provides the adjustable tap.

Manufacturer

- Manufacturer: Microchip Technology Inc.
- What kind of company: A US-based multinational semiconductor company that designs, manufactures, and sells microcontrollers, analog and mixed-signal ICs (including digital potentiometers like MCP4716), memory, and related solutions. It is publicly traded on NASDAQ (ticker: MCHP) and headquartered in Chandler, Arizona.

Application

MCP4716A0T-E/MAY is a single-channel, I2C-controlled, 8-bit volatile digital potentiometer. Key application areas:
- Adjustable gain/attenuation and offset trimming in op-amps, ADC/DAC front ends, and instrumentation
- Programmable volume control in audio equipment
- Sensor calibration and field offset/gain compensation
- Programmable feedback networks and reference resistor tuning in microcontroller-based designs
- Any design needing a replaceable, calibratable resistor network for tuning and calibration

Package

It comes in an 8-pin MSOP package (MSOP-8). Check the datasheet for exact variant (RoHS, tape-and-reel options, etc.).
