Cs, Cps
1
μF
Supply decoupling capacitor that provides power supply filtering.
Cb
1
μF
Bypass decoupling capacitor that provides half-supply filtering.
Cin
1
μF
Input coupling capacitors that block the DC voltage at the amplifier
input terminal. The capacitors also form a high-pass filter with Zin.
Cinbeep
47nF
Input coupling capacitors that block the DC voltage at the PCBEEP
input terminal. The capacitors also form a high-pass filter with Rin.
Rin
47k
Ω
Inverting input resistor for PCBEEP input. Together with the internal
47 k
Ω feedback resistor the PC beep input gain can be adjusted to
change a voltage detection level.
Cp
1
μF
Flying capacitor for the negative charge pump.
