Product Overview

The INA138NA/250 is a high-side unipolar Current Shunt Monitor for use with battery-backup systems. Input common-mode and power-supply voltage is independent and can range from 2.7 to 36V. Quiescent current is only 25µA, which permits connecting the power supply to either side of the current measurement shunt with minimal error. The device converts a differential input voltage to a current output. This current is converted back to a voltage with an external load resistor that sets any gain from 1 to over 100. Although designed for current shunt measurement, the circuit invites creative applications in measurement and level shifting.
  • Wide input common-mode voltage range
  • Complete unipolar high-side current measurement circuit
  • Single resistor gain set
  • 25µA Typical low quiescent current
  • Green product and no Sb/Br
