The BA5415A and BA5416 are dual power amplifier ICs that operate off a 9V to 15V supply. When driving a 4W load off a 9V supply, the BA5415A does not require a heatsink. The BA5416 uses a low-cost package. The basic characteristics (total harmonic distortion etc.) of the amplifiers are excellent, and both ICs include a standby switch function.
