Description

Product Overview

The DS4422N+T&R from Maxim is a 2-channel 7-bit I2C DAC with 50 µA to 200 µA sink/source output current range. It is designed for power supply margining and offset adjustment in server and networking equipment.

Key Specifications

Function I2C 2-channel 7-bit DAC
Channels 2
Resolution 7-bit (128 steps)
Interface I2C
Output Current 50 µA to 200 µA sink/source
Supply Voltage 3.0V to 5.5V
Package TDFN-8 (2x2mm)

Working Principle

Two 7-bit current DACs sink or source current from/to an external FB node of a DC-DC converter, adjusting the output voltage above or below nominal. The MSB of each 7-bit value sets direction (sink/source), the remaining 6 bits set magnitude. This enables ±margin adjustment for power supply validation testing.

Applications

  • Power supply margining
  • DC-DC output voltage trim
  • Sensor offset adjustment
  • Server PSU calibration
