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:

the input offset voltage Vos

the non-linearity

the voltage saturation of VOL and VOH

The output voltage accuracy, expressed as a percentage, can be calculated with the

following formula.

With Av = 20 V/V for TSC1021A and Av = 50 V/V for TSC1021B.
