Output voltage accuracy
The output voltage accuracy is the difference between the actual output voltage and the
theoretical output voltage. Ideally, the current sensing output voltage should be equal to the
input differential voltage multiplied by the theoretical gain, as in the following formula:
The actual value is very slightly different, mainly due to the effects of:
