3 / 6 page LA42051 No.A1037-3/6 Block Diagram Test Circuit Description of External parts C1 : Input coupling capacitor, for which 1.0 μF is recommended. The potential of input pin is 2VBE (about 1.4V). Therefore, the polarity must be determined according to the DC potential of the circuit connected to the previous step of LA42051. C2 : Capacitor for ripple filter, for which 100 μF is recommended. C3 : Capacitor for attenuation of pop noise, for which 4.7 μF is recommended. C4 : Power supply capacitor. C5 : Output capacitor, for which 470 μF is recommended. Determine the constant while taking into account a fact that, with the capacitance set to 470 μF or less, the roll-off frequency decreases in the low range.
