TA8221AHQ Overview
is made only on the single channel.) 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.
