CHAPTER 2. TECHNICAL DESCRIPTION
2-14
4-4 Audio Signal Flow
< AIF >IC801
Carries out switching between internal and external microphones (by means of serial data from MODE MI-COM),plus ALC (Auto
Level Control), fading, and amplification of various output signals. For the beep tone issued at ejection, etc., the signal from the FR
MI-COM is generated in the circuit and changed over in the AIF.
The microphone amplifier, HPF, ALC, A/D, D/A, and digital I/F circuits are contained in this IC. It is also used for changeover
between ordinary voice sound and beep sound.
< SPEAKER DRIVER >IC802
This integrated circuit is used for speaker drive operation.
