4.5 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 V

● non-linearity

theoretical and actual characteristics
The output voltage accuracy, expressed in percentage, can be calculated with the following
formula:
with A
v
= 20 V/V for TSC101A, A
v
= 50 V/V for TSC101B and A
v
= 100 V/V for TSC101C.
