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:
V_out-th=A_v V_sense
The actual value is very slightly different, mainly due to the effects of:
• the input offset voltage V_os,
• non-linearity

The output voltage accuracy, expressed in percentage, can be calculated with the following
formula:
ΔV_out
=
a----b----s---(_{---V----o---u----t---}–_----(_{---A----v----}⋅_{----V----s---e----n---s---e---})_---)
A_v ⋅ V_sense
with A_v = 20 V/V for CS30A, A_v = 50 V/V for CS30B and A_v = 100 V/V for CS30C.
