TA8220H - 30W BTL x 2CH AUDIO POWER AMPLIFIER

Description

1.

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).

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 output short detection circuit, output clip detection and various kind of protection. Features.
  • Low thermal resistance: θj.
  • T = 1.5°C / W (infinite heat sink).
  • High power: POUT (1) = 30W (typ. ) / channel (VCC = 14.4V, f = 1kHz, THD = 10%,.
