Output pins
Output transistor ground
Feedback can be applied to the control amplifier by
inserting resistor between this pin and GND and detecting
the output current as a voltage. The overcurrent
protection circuit (current limiter) operates by detecting
the voltage on this pin.
Power supply provided to all blocks other than the output
block
This voltage must be stabilized so that no ripple or other
noise is present.
The current limiter operates when the R
f
pin reaches the
same potential as pin 12. The pin 12 potential is set up
externally.
Control input to output gain switching pin
High level (4 to 5 V): 34 dB
Middle level (2 to 3 V) or open: 40 dB (low speed):
34 dB (high speed)
Low level (0 to 1 V): 40 dB
However, note that this applies when V
CC
2 is 5 V.
