3. After setting V
Vimax Maximum input
Measuring conditions are the same as those used above, except
that the setting of V17 is changed to 2.5V as specified in
Supplementary Table. Increase the input signal amplitude gradually,
starting from 700mV
signal starts becoming distorted.
Gv Maximum gain
1. Input SG6 to pin 13 (8 or 3), and read the amplitude at output
2. Maximum gain G
3. Relative maximum gain G is calculated by the equation below:
V
