MCP4728 in Microchip MCP4725 DAC Family
The MCP4728 is a quad-channel, 12-bit voltage output digital-to-analog converter (DAC) developed by Microchip Technology. It expands upon the MCP4725 series by offering four independent output channels in a compact 10-pin MSOP package. It features integrated non-volatile memory (EEPROM), allowing the device to retain DAC register settings and configuration bits during power-down cycles, making it ideal for systems requiring specific power-up states without immediate microcontroller intervention.

Variants within the MCP4728 sub-family are primarily distinguished by their factory-programmed I2C address bits and temperature ratings. The standard E/UN suffix denotes an extended temperature range (-40°C to +125°C) in a 10-lead MSOP package. Engineers can select specific device address codes to allow multiple MCP4728 devices to coexist on the same I2C bus without address conflicts, supporting up to eight unique devices for a total of 32 analog channels.
