MCP4725 is a 12-bit single channel, low power, high accuracy, digital to analog converter (DAC) with non-volatile memory (EEPROM) from Microchip Technology Inc.
The MCP4725 is a single‑channel, 12‑bit buffered voltage‑output DAC that includes on‑board EEPROM to retain the output code during power‑off. It operates from a single 2.7 V to 5.5 V supply and provides rail‑to‑rail output swing with low power consumption.
Key features include a two‑wire I²C‑compatible serial interface (standard 100 kHz, fast 400 kHz, high‑speed 3.4 MHz), fast 6 µs settling time, and a compact SOT‑23‑6 package. Electrical specifications such as resolution, power‑down current, and EEPROM endurance are detailed in the datasheet.
