YDA131
■Application circuit
Outline of components that are connected externally to this IC.
CP1, CP3
Capacitors for stabilization of the power supply
CP2, CP4, RP2, RP4
Capacitors and resistors for stabilization of the power supply (snubber)
CR1
Capacitor for stabilization of reference voltage, and capacitor for stabilization of starting.
CI
Input AC coupling capacitor: RI and CI form a high pass filter.
RI
Inversion input resistor that determines the gain.
RF
Feedback resistor for determining the gain.
CF
Capacitor for input low pass filter.
LO
Output inductance: Being combined with CO, the component forms the secondary filter that
removes the high frequency and delivers an amplified audio signal to the load.
CO
Output capacitor
DS
Shottkey-diode for terminal protection (equivalent to 11EQS04)
