*3 Instantaneous common mode rejection voltage
output(0)
*1. Current transfer ratio is the ratio of input current and output current expressed in %.
*2. Measured as 2-pin element ( Short 1, 2, 3, 4 and 5, 6, 7, 8 )
*3 Instantaneous common mode rejection voltage "output (1)" represents a common mode voltage variation
that can hold the output above (1) level (Vo>2.0V).
Instantaneous common mode rejection voltage "output (0)" represents a common mode voltage variation
that can hold the output above (0) level (Vo<0.8V).
