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.

Features

due to the temperature rise at the high output can also be reduced. This stereo audio power IC, designed for car audio use, has two built−in channels to reduce the characteristic difference between L and R channels. It also contains various kind of protection. TA8221AHQ TA8221ALQ Features
