(Note1)
The center frequency characteristics of BPF are determined by the
resistor connected between 3PIN terminal and GND.If it is necess-
ary,use a variable resistor (note:all band will shift together).
Q of BPF is fixed in 3.5 by inside circuit.
(note 2)
The output resistor of peak hold output(PIN 15) is 10KΩtyp.
You do the input resistor of microprocessor side in a value fully big
for 10KΩ.
(note 3)
Set up as the control voltage from a microprocessor during GND-0.3V
and 5V.
If the voltage of tolerance outside is added, conserve it resistance
or diode.
