Description

The MCP4726A3T-E/CH is Microchip’s single‑channel, 12‑bit digital‑to‑analog converter (DAC) with I2C interface. It converts a 12‑bit digital code from a microcontroller into a precise analog voltage (0 to VREF or VDD, depending on the reference). Key features include:
- 12‑bit resolution, I2C interface
- Volatile DAC register plus nonvolatile memory to retain the value after power‑up
- Low power with optional programmable power‑down modes
- Buffered output (low source impedance)
- Operating supply typically in the 2.7–5.5 V range
- 7‑bit/3‑bit I2C addressing based on A0–A2 pins
- 8‑pin package; variant and packaging indicated by the A3T‑E/CH suffix (industrial/lead‑free options, etc.)
Common uses: calibration, sensor signal conditioning, reference generation, automated test equipment. For exact electrical specs, timing diagrams, and pinout, consult the MCP4726A3T‑E/CH datasheet.

Features

Key features of MCP4726A3T-E/CH (Microchip):
- Dual 12-bit DAC channels with I2C interface
- Buffered voltage outputs for each channel
- Non-volatile memory to store last output values
- 0 to VDD output range (uses supply as reference)
- Operating supply: typical 2.7–5.5 V
- I2C data rate up to 400 kHz (Fast-mode)
- Small 8-pin package (CH variant)
- Low quiescent current and available power-down modes
- Addressable/configurable I2C address options (via hardware pins)
Note: For exact electrical specs (tolerances, offsets, drift, and temperature range), please consult the official datasheet.

Package

8-pin MSOP package.

Pinout

Pin count: 8 pins.
Function: Dual, 12-bit, I2C-controlled digital-to-analog converter (DAC) with two outputs (VOUTA and VOUTB). Includes I2C interface (SCL, SDA) and address pins (A0, A1) to set the device address, plus power (VDD) and ground (GND).

Manufacturer

- Manufacturer: Microchip Technology Inc. (Microchip).
- What kind of company: A US-based semiconductor company that designs and manufactures microcontrollers, analog ICs, memory, and other embedded control solutions; publicly traded on NASDAQ (MCHP).

Application

Typical applications: I2C-controlled 12-bit DAC to generate precise DC voltages for ADC calibration and offset/gain trim; programmable voltage references; calibration and signal conditioning in test/measurement and instrumentation; analog control signals for microcontroller systems (LED dimming, sensor simulators, motor control); nonvolatile storage of calibration data for power-cycle retention.
