Audio ICs

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 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.) of the amplifiers are excellent, and both ICs include a standby switch function.

Applications
Radio cassette players.

Features

1) High output.
P

OUT = 5.4W (VCC = 12V, RL = 3Ω and THD = 10%)

P

OUT = 2.5W (VCC = 9V, RL = 4Ω and THD = 10%)

2) Excellent audio quality.
THD = 0.1% (f = 1kHz, P

NO = 0.3mVrms (Rg = 10kΩ)

RR = 60dB (f

3) Wide operating power suppy voltage range.

CC = 5.0V to 18.0V (BA5416: 5.0V to 15.0V)

RR = 100Hz)

O = 0.5W)

4) Switching noise (“pop” noise) generated when the
power is switched on and off is small.

5) Ripple mixing when motor starts has been pre­vented.

6) Built-in thermal shutout.

7) Built-in standby switch. Output is not influenced by
the standby pin voltage.

8) “On” mute time does not depend on V

9) Soft clipping.

10) Heatsink not required (for BA5415A, with V
