(2) Frequency characteristics

The frequency characteristics for this IC are set by an ex-

ternal resistor. The value of this resistor for the specifica-

tion conditions is 120kΩ. Use a potentiometer if you wish

to set the frequency characteristics accurately.

(3) Operating voltage range

Operation of the application example circuit is guaran-

teed provided that the VCC and Vee voltages are within

the specified power supply voltage range, and the ambi-

ent temperature is within the specified range. With regard

to the characteristic values, the output voltage level will

differ from the rated values for the specification condi-

tions if the power supply voltage is reduced, but the in-

herent function of the band-pass filters is preserved.

(4) Load resistance

The various circuit characteristics in this specification

sheet were measured using an output load resistance of

10kΩ. If the load resistance is too low, the I / O gain and

control range vary slightly. Be aware of this when con-

necting the next stage.

(5) Coupling capacitors

Set the polarity of the input electrolytic coupling capaci-

tors after establishing the electrical potential relationship

with the connected input.
