4.1 Quick Start Setup

Follow these procedures to set up and use one of the INA2290EVM panels. For these instructions, n is gain option 1, 2, 3, 4, or 5.

  1. Choose the desired gain option panel variation.
  2. Connect an external DC supply voltage (between 2.7 V and 20 V) to a VS test point. Connect the ground reference of that supply to a GND test point on the same panel.
  3. Provide a differential input voltage signal to the In+ and In– nodes by connecting the signal leads to the J1_n pin 1 and J1_n pin 2 for channel 1 or J2_n pin 1 and J2_n pin 2 for channel 2 on the EVM, as explained in Section 4.2. The INA2290 is a unidirectional current-sensing device because there is no reference pin. The device can only measure current in one direction.
