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.
