Op-amplifier output pin.
This op-amplifier can be used for :
1. Control gain changing, or
2. FG amplifier.
A resistor connected between this pin and pin 20
(VCIN) enables pin 22 switching between HIGH level
and open to switch the op-amplifier gain.
When the voltage on Rf pin becomes equal to the
voltage on pin 12 (CL), the current limiter operates.
The pin 12 (CL) voltage is determined externally.
If the current limiter is not used, it should be
connected to VCC2
When this pin goes HIGH, the resistor connected
between pins 18 and 20 is connected in parallel with
the op-amplifier feedback resistor to switch the gain.
Op-amplifier inverting input pin.
The op-amplifier non-inverting input is connected to
pin 4 VCREF
Control input gain switching pin.
35dB is selected when pin 13 (GC) is HIGH (4 to 5),
and 29dB is selected when pin 13 (GC) is LOW (0 to
2V) or open for a value VCC2=5V.
