... High-output dual power amplifier BA5415A / BA5416 The BA5415A and BA5416 are dual power amplifier ICs that operate off 15V supply. When driving a 4Ω load off a 9V supply, the BA5415A does not require a heatsink. The BA5416 uses a lost-cost package. The basic characteristics (total harmonic distortion etc ...

... IC is guaranteed regulation characteristics (including the capacitance of the power supply capacitor connected between V GND) so that V is 18.0V or less (15.0V or less for the BA5416). If the IC is inserted backwards reversed and the IC will be destroyed instantly the standby switch will not adversely influence circuit ...
