INA225 Evaluation Module for 36-V Programmable-Gain, Current Shunt Monitor



  •  Jumper selectable Gain (25,50,100,200)
  •  Optional input filter
  •  Allows for the INA225 to be used in both unidirectional and bidirectional applications

Texas Instruments  INA225EVM

The INA225 is a voltage output current-shunt monitor that senses drops across shunts at common-mode voltages from 0V to 36V, independent of the supply voltage. The four gain versions are selectable using the 2 external gain select pins, GS0 and GS1. These pins allow a gain of 25, 50, 100, and 200 to be selected. The low-offset zero-drift architecture enables current sensing with voltage drops across the shunt as low as 10mV of full-scale while maintaining high accuracy measurements. The INA225EVM is a platform for evaluating the performance of the INA225 under various signal, shunt, and supply conditions.  This document gives a general overview of the INA225EVM, and provides a general description of the features and functions to be considered while using this evaluation module.
