5 4W Dual Audio Power Amplifier


General Description:
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.
Features

  • High output.
  • POUT = 5.4W (VCC = 12V, RL = 3Ω and THD = 10%)
  • POUT = 2.5W (VCC = 9V, RL = 4Ω and THD = 10%)
  • Excellent audio quality.
  • THD = 0.1% (f = 1kHz, PO = 0.5W)
  • VNO = 0.3mVrms (Rg = 10kΩ)
  • RR = 60dB (fRR = 100Hz)
  • Wide operating power supply voltage range.
  • VCC = 5.0V to 18.0V (BA5416 : 5.0V to 15.0V)
  • Switching noise (ìpopî noise) generated when the power is switched on and off is small.
  • Ripple mixing when motor starts has been prevented.
  • Built-in thermal shutout.
  • Built-in standby switch.
  • Output is not influenced by the standby pin voltage.
  • Mute time does not depend on VCC.
  • Soft clipping.
  • Heatsink not required  (for BA5415A, with VCC = 9V and RL ≥ 4Ω).
