wind noise elimination.
On-chip external power supply (with a current limiter).
Capacitors=less than 1.0
F (excluding ripple filters).
Stereo/monaural detect output pin for external MICs.
Functions
2-channel microphone amplifiers.
Internal MIC power supply (2 channels).
Internal/external MIC select switch.
External power supply (with a current limiter).
HPF (with a through switch).
External MIC stereo/monaural detector.
Ripple filter.
