... 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 ...
