The BA5415A and BA5416 are dual power amplifier ICs that operate off a 9V to 15V supply. When driving a 4 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.
FApplications
Radio cassette players.
FFeatures
1) High output.
2) Excellent audio quality.
3) Wide operating power suppy voltage range.
FAbsolute maximum ratings (Ta = 25_C)
FRecommended operating conditions (Ta = 25_C)
