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 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= 0.3mVrms(Rg = 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.
