... TOSHIBA Bipolar Linear Integrated Circuit Silicon Monolithic 30W BTL × 2ch Audio Power Amplifier The thermal resistance θj−T of TA8233BHQ package designed for low thermal resistance, has 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 ...

... Block Diagram TA8233BHQ (G = 50dB) V Caution And Application Method (description is made only on the single channel.) 1. Voltage gain adjustment This IC has the amplifier constructions as shown in 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− ...
