TA8221ALQ - Audio Power Amplifier

Download the TA8221ALQ datasheet PDF. This datasheet also covers the TA8221AHQ variant, as both devices belong to the same audio power amplifier family and are provided as variant models within a single manufacturer datasheet.

General Description

This IC has the amplifier construction as shown Fig.1.

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).

Key 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.
  • 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%, RL =2Ω) POUT (2) = 26W (typ.
