Functional description

Input coupling capacitors that block the DC voltage at the amplifier input

terminal.

Output coupling capacitors that block the DC voltage coming from the

amplifier output terminal (pins C2 and D2) and determine Lower cut-off

frequency.

These output resistors can be represented by an input impedance of a

following stage.

Polarizing resistors for biasing of a microphone.

Supply bypass capacitor that provides power supply filtering.

Bypass pin capacitor that provides half-supply filtering.

Low pass filter capacitors allowing to cut the high frequency.
