W20NB50 - STW20NB50

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.

TA8221AHQ / ALQ TOSHIBA Bipolar Linear Integrated Circuit Silicon Monolithic TA8221AHQ,TA8221ALQ 30W BTL × 2Ch Audio Power Amplifier The thermal resistance θj−T of TA8221AHQ, TA8221ALQ package designed for low thermal resistance, has a high efficiency of heat radiation. The temperature rise of chip can be reduced, and the influence from the degradation of the 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.
