Overview

Description

The MCP4728T-E/UN is a quad-channel, 12-bit digital-to-analog converter (DAC) from Microchip. It features four independent voltage outputs with internal non-volatile memory (EEPROM) for storing settings. Key specifications include:
- Resolution: 12-bit (4096 steps)
- Channels: 4 (individually configurable)
- Interface: I²C (up to 3.4 MHz)
- Supply Voltage: 2.7V to 5.5V
- Output Range: Rail-to-rail (0V to VDD)
- Internal EEPROM: Retains settings on power-off
Applications include industrial control, test equipment, and programmable voltage references. The device supports software shutdown and per-channel gain/voltage reference selection (internal or external). Its compact TSSOP-16 package makes it suitable for space-constrained designs.
