MCHPMCP4728-E/UN
Overview
The MCP4728-E/UN is a quad-channel, 12-bit voltage output digital-to-analog converter (DAC) featuring integrated non-volatile memory (EEPROM). This device operates over a 2.7V to 5.5V supply range and uses a two-wire I2C interface, making it ideal for systems requiring multiple precise analog control signals from a single digital bus.
Why Choose This Part
The primary advantage is the integrated 16-byte EEPROM, which allows the DAC to retain its output states and configuration across power cycles. Its quad-channel density in a compact 10-MSOP package reduces board space while providing buffered voltage outputs that simplify circuit design.
Applications
Key Specifications
Getting Started
Engineers can interface the MCP4728 with any standard I2C controller to read/write the internal registers and EEPROM. When prototyping, ensure the LDAC pin is managed correctly to synchronize multi-channel updates, and utilize the internal 2.048V reference for stable output performance without external components.
