Rf
Ground for the output transistors
The output current can be detected as a voltage by connecting a
resistor between the Rf pin and ground. This can then be used to
implement overcurrent protection.

Power supply for circuits other than the output block
The power supply provided by this pin must be well stabilized so
that noise does not occur.

Connections for the resistors that set the front-end amplifier gain
Z1 and Z2 are common, and have a resistance of between a few
tens of k
and a few hundreds of k
.
The gain is about 6 dB.

I/O gain switching input
GC1 switches Z1 and Z2 for the front end amplifier. When GC1 is
low, Z1 is selected, and when GC1 is high, Z2 is selected. GC2
switches the amplifier in the second stage.
