1. Voltage gain adjustment
This IC has the amplifier constructions as shown Fig.1. The pre−amp (amp1) is provided to the primary stage,
and the input voltage is amplified by the flat amps, amp3 and amp4 of each channel through the phase amp
(amp2).
Since the input offset is prevented by pre−amp when V
