(2) REC amplifier
The REC amplifier in this IC is for FM audio. Take note
of the following points in order to maintain its common-
mode distortion characteristics.
1)Connect the REC AGC FILTER (pin 13) and CUR-
RENT SENSE (pin 14) to the main GND of the IC (pin
16) using leads that are as short as possible.
2)REC NF (pin 11) should be as close to the main IC
GND as possible.
3)If you connect a resistor to pin 23 or between pins
24 and 15 to monitor the recording current, the result-
ing voltage drop may cause the IC to function incorrect-
ly. Use the current sense pin (pin 14) to monitor the
recording current.
