Audio amplifier circuit

3-4. Audio amplifier circuit

The demodulated signal from IC12 goes through the mute

switch (Q15) and is amplified by IC4 (2/2), high-pass filtered,
low-pass filtered, high-pass filtered, band-eliminate filtered, and
de-emphasized by IC13.

The signal then goes through an AF amplifier IC7 (2/2), an

electronic volume control (IC8), and an AF switch (Q310 is
on), and is routed to audio power amplifier (IC300), where it is
amplified and output to the internal speaker.

The audio mute signal (AM) from the shift register becomes

Low in the standby and Q304, Q305 which are power supply
circuit for IC300 turn off. Also, IC13 is set to the power down
mode according to data from microprocessor, and the AF signal
is muted. When the audio is output, AM becomes High to turn
Q304, Q305 ON, and voltage is supplied to power terminal VP
of IC300. Also, IC13 is canceled out of the power down mode.

The speaker is switched by the logic of speaker switching

terminal SSW on the universal connector. When SP-MIC is
not attached, the logic of SSW becomes High and SW (Q310)
is turned ON, and the AF signal is input to both amplifiers of
IC300.

When SP-MIC is attached, SSW is connected to GND at

inside of SP-MIC. For this reason, Q310 is turned OFF, and
the AF signal is input only to amplifier for EXT SP of IC300.

Change of INT/EXT SP refer to Fig. 4.

3-5. Squelch circuit

The output from IC12 enters FM IC again, then passed

through a band-pass filter. The noise component output from
IC12 is amplified by Q4 and rectified by D4 to produce a DC
voltage corresponding to the noise level. The DC voltage is
sent to the analog port of the CPU (IC19). And IC12 outputs a
DC voltage (RSSI) corresponding to the input of the IF amplifier.
The CPU reads the RSSI signal via pin 93.

IC19 determines whether to output sounds from the speaker

by comparing the input voltage of pin 91 and pin 93 with the
preset value.

4-1. Microphone amplifier

The signal from the internal microphone goes through the

mute switch (Q300).

When the SP-MIC is not attached, the microphone switching

terminal (MSW) on the universal connector becomes High, and
mute switch (Q300) is turned ON. When the SP-MIC is
