BA5416

高输出双功放 High-output dual power amplifier

The BA5415A and 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 characteris tics total harmonic distortion etc. of the amplifiers are excellent, and both ICs include a standby switch function.

Features

1 High output.

  POUT= 5.4W VCC= 12V, RL= 3Ωand THD = 10%

  POUT= 2.5W VCC= 9V, RL= 4Ωand THD = 10%

2 Excellent audio quality.

  THD = 0.1% f = 1kHz, PO= 0.5W

  VNO= 0.3mVrmsRg = 10kΩ

  RR = 60dB fRR= 100Hz

3 Wide operating power suppy voltage range.

    VCC= 5.0V to 18.0V BA5416: 5.0V to 15.0V

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 VCC.

9 Soft clipping.

10 Heatsink not required for BA5415A, with VCC= 9V and RL 4Ω.

Applications

Radio cassette players.
