Power Supply terminal
Volume circuit
Volume up, down control input pin.
The 1 step / 1 push volume is controlled by pushing
the Up or Down key . If the key has been pushed
continuously, the continuous volume control.
These two input pins have built-in pull-up resistor.
Oscillation pin.
Oscillator circuit consist of C.R connection.
Oscillation is executed while key is pushed.
Input pin for setting initial volume level volume level
set to 46dB by "L" input.
This input pin has built-in pull-up resistor.
Back up mode input pin.
Internal all operation is stopped by "L" input, and
volume level remains with low current consumption.
DC output pin for volume level meter.
DC voltage which is corresponded to volume step is
generated.
