Product Overview

The MAX4073FAXK+T is a low cost, voltage output, high side current sense amplifier with +50V/V gain in 5 pin SC-70 package. The voltage output of this device eliminates the need for gain setting resistors which makes this device as ideal for applications where current monitoring is crucial. High side current monitoring does not interfere with ground path of battery charger making the MAX4073F particularly useful in battery powered systems. The input common mode range of +2V to +28V is independent of supply voltage. The wide 1.7MHz bandwidth of MAX4073F makes it suitable for use inside battery charger control loops. The combination of fixed gain and selectable external sense resistor sets the full scale current reading. It offers high level of integration resulting in simple and compact current sense solution. The device is used in PA bias control, general system/board level current monitoring and precision current sources.
  • Supply voltage range from 3V to 28V
  • Automotive temperature range from -40°C to 125°C
  • Low cost and compact current sense solution
  • ±1% gain accuracy at TA = +25°C (VCC = 12V, VRS+ = 12V, VSENSE = 10mV to 150mV)
  • Supply current of 500µA at VCC = 28V
  • Common mode rejection ratio (CMRR) of 90dB at VSENSE = 100mV, VCC = 12V
  • Input bias current of 40µA
  • Power supply rejection ratio of 85dB at VCC = 3V to 28V, VSENSE = 24mV
  • Extrapolated input offset voltage of 1mV at VCC = VRS+ = 12V, VSENSE > 10mV
