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