3.3 Quick Start Setup

The following instructions describe how to set up and use the EVM.

  1. Connect an external dc supply voltage between 2.7 V and 5.5 V to the VS test point, and connect the ground reference of that supply to the GND test point.
  2. Connect a current source across the IS+ and IS– test points, to provide current flowing through the integrated shunt resistor. The common-mode voltage on the IS+ and IS– pins must be between –4 V and +80 V (referenced to the GND pin).
  3. The OUT pin quiescent voltage level is midsupply, and increases or decreases when there is a current load flowing through IS+ and IS–, as set up in the previous step.
