Product Overview

The MAX44285TAUA+ from Maxim Integrated Products is a dual channel, high precision, high voltage, current sense amplifier in 8 pin µMAX package. This dual channel high side current sense amplifier has precision accuracy specifications of VOS less than 12μV (maximum) and gain error less than 0.1% (maximum). The MAX44285T features an input common mode voltage range from 2.7V to 76V with 80KHz of small signal bandwidth which makes it ideal for interfacing with a SAR ADC for multichannel multiplexed data acquisition systems. It is typically used in base stations and communication equipment, power management systems, server backplanes, industrial control and automation.
  • Gain is 20V/V
  • Supply voltage from 2.7V to 5.5V
  • Supply current of 1300µA at TA = +25°C
  • Power supply rejection ratio of 120dB at 2.7V ≤ VDD ≤ 5.5V
  • Input bias current (at VRS+ and VRS-) of 65µA and input offset current of 1100nA
  • Common mode rejection ratio of 140dB at 4.5V < VRS+ < 76V
  • Input offset voltage of ±12µV at TA = +25°C, input sense voltage of 125mV
  • Output resistance of 0.1mohm
  • Operating temperature range from -40°C to +125°C
  • 80KHz signal bandwidth
  • Base Stations and Communication Equipment; Industrial Control and Automation; Power Management Systems; Server Backplanes
