TA8221AHQ / ALQ
Cautions And Application Method
(description is made only on the single channel.)
1. Voltage gain adjustment
This IC has the amplifier construction as shown Fig.1. The pre−amp (amp 1) is provided to the primary stage,
and the input voltage is amplified by the flat amps, amp 3 and amp 4 of each channel through the phase amp
(amp 2).
Since the input offset is prevented by pre−amp when VCC is set to on, this circuit can remarkably reduce the pop
noise.
