Hi ~

One question for INA233 accuracy, I want to know how to calculate the current sense accuracy?

Below is our test condition.

Voltage: 5.0V

Current: 1.5A

sense resistor tolerance: 1%

Hello Bob,

To learn more about error and accuracy in current sense amplifiers, please refer to our video series: https://training.ti.com/ti-precision-labs-current-sense-amplifiers-error-sources?

Note video 3.7 is about shunt resistor tolerance error. Also, since this part is digital, you will need to take into account the LSB of the measurement data.
