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).
