MCHPMCP4725A0T-E/CH
Overview
The MCP4725A0T-E/CH is a 12-bit, single-channel voltage output Digital-to-Analog Converter (DAC) featuring integrated nonvolatile memory (EEPROM). This resistive string DAC operates over a 2.7V to 5.5V supply range and includes a rail-to-rail buffered output, making it a versatile choice for precision analog signal generation. The internal EEPROM allows the device to store configuration bits and DAC input codes, ensuring the output remains consistent even after a power cycle.
Why Choose This Part
A key advantage is the integrated EEPROM, which enables the DAC to retain its output state and configuration across power resets without host intervention. Its SOT-23-6 package provides high performance in a minimal PCB footprint, while the I2C interface simplifies wiring by sharing the bus with other sensors.
Applications
Key Specifications
Getting Started
To evaluate the device, engineers often use the MCP4725 Evaluation Board or an Adafruit MCP4725 breakout connected to an Arduino or similar MCU via the I2C pins. Communication involves simple 2-wire commands to set the 12-bit value, and the A0 address pin can be used to resolve bus conflicts by toggling between two available I2C addresses.
