Part
Function
Comments
R1
Microphone power supply decoupling
Reduces power supply noise
R2
Release time constant
Sets release time for AGC
R3, R5
Microphone biasing resistors
Provides biasing for microphone operation
R4
Series limiting resistor
Reduces level to prevent distortion at
higher supply voltages
R6
Series limiting resistor
Reduces level to high supply voltages
C1, C5
Microphone DC-blocking capacitor Low-
frequency cutoff
Decouples microphone bias from chip.
Provides single-pole low-frequency cutoff
and command mode noise rejection.
C2
Attack/Release time constant
Sets attack/release time for AGC
C3
Low-frequency cutoff capacitor
Provides additional pole for low-frequency
cutoff
C4
Microphone power supply decoupling
Reduces power supply noise
C6, C7, C8
Power supply capacitors
