High-output dual power amplifier
BA5417
The BA5417 is a 6 to 15V-compatible dual power amplifier developed for use radio cassette players. It is equipped with
standby switching functions for excellent total harmonic distortion and other basic characteristics.
!Applications
Radio cassette / Mini compo players
!Features
1) High output.
POUT = 2.8W (VCC = 9V, RL 3Ω, THD = 10%)
POUT = 5.0W (VCC = 12V, RL 3Ω, THD = 10%)
2) Excellent audio quality
THD = 0.1% (f = 1kHz, PO = 0.5W)
VNO = 0.3mVrms (Rg = 10kΩ)
RR = 55dB (fRR = 100Hz)
3) Wide supply voltage operating range
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 shutdown circuit.
7) Built-in standby switch. Output is not influenced by
the standby pin voltage.
8) Soft clipping.
(VCC = 6.0V to 15.0V).
