2.1 V
External power supply with current limiter
Capable of providing at least 4 V when an output
current is 25 mA.
When the output voltage is 0 V, the output current is
less than 25 mA.
Detects the level used to turn the high-pass filter on
and off.
Reference voltage
Outputs a low level only when the external
microphone is monophonic.
Microphone amplifier output
This is a low-impedance output.
Internal/external switch
Control pin used to determine stereo or monophonic
operation
