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 3, THD = 10%) POUT = 5.0W (VCC = 12V, RL 3, THD = 10%) 2) Excellent audio quality THD = 0.1% (f = 1kHz, PO = 0.5W) VNO = 0.3mVrms (Rg = 10k) RR = 55dB (fRR = 100Hz) 3) Wide supply voltage operating range (VCC = 6.0V 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 shutdown circuit. 7) Built-in standby switch. Output is not influenced by the standby pin voltage. 8) Soft clipping.
