Visão Geral

Description

The MCP4716A3T-E/MAY is Microchip’s I2C digital potentiometer with a 6-bit (64-step) wiper. It provides a programmable resistance between terminals A and B with a wiper (W) controlled over I2C, suitable for electronically adjusting analog signals (gain, offset, attenuators, etc.). The wiper value is stored in a volatile register (lost on power-down unless used with a separate nonvolatile variant). It operates from 2.7 to 5.5 V, with up to 8 devices on a bus via address pins, and I2C speeds up to 400 kHz. End-to-end resistance options vary by variant; check the exact part for the RAB value (e.g., 5k/10k/50k options). The suffixes -E indicates RoHS-compliant, -T generally denotes Tape & Reel packaging, and -MAY is the specific packaging/date code for this lot. Typical uses include volume control, sensor calibration, and adjustable signal conditioning in microcontroller projects. For precise specs, refer to the MCP4716A3T data sheet.

Features

Here are the typical features of the MCP4716A3T-E/MAY (digital potentiometer):
- I2C-compatible interface (two-wire serial control) with a single potentiometer
- 8-bit wiper resolution (256 steps)
- End-to-end resistance options available (e.g., 10 kΩ, 50 kΩ, 100 kΩ) per variant
- Operating supply range roughly 1.8–5.5 V
- Addressing via hardware pins (A0/A1) for multiple devices on the bus
- Wiper position stored in a volatile register (updates take effect immediately)
- Low-power operation with relatively small current draw
- Temperature range typically around -40°C to +125°C (industrial/ automotive-grade variants)
- Pb-free, RoHS-compliant packaging (8-pin packages such as SOIC/MSOP)
Note: Exact end-to-end resistance option, temperature range, and package variant depend on the specific part revision; consult the datasheet for the precise specifications of your device.

Pinout
