INA223EVM Software Overview

5.3.3

Example Hardware Calculator

The Example Hardware Calculator tab allows the user to simulate the analog results of the INA223EVM.

By adjusting the controls on this page, and entering inputs for Vin+ (V), Vin- (V), and Rshunt, the

approximate values for Vout (V) and Power (W) can be estimated. Note that the appropriate output mode

must be selected to ensure accurate results, and that no limitations of the device are violated in the Error

field.

This calculator is used to help ensure that the physical output and settings are operating correctly. The

EVM and device digital communication interface are only designed to configure the device settings. There

is no analog readback available with this EVM. This means that the output voltages shown on this

calculator tab in the software are calculated results based on the parameters entered and not

representative of the measurements of the actual device.
