Sample Printed Circuit Pattern (Cu-foiled area)
IC Usage Notes
(1) It is recommended to connect a surge absorbing capacitor across input pins 1, 2 and GND and across input pins 19, 20 and
GND.
(2) The base of a PNP transistor is connected to input pins 1, 2 and 19, 20. If an electrolytic capacitor is connected in series with
the input pins, connect input resistor R
IN
must not exceed 500 k
. (Reason: To minimize the variation in output DC voltage
at the time of input switching)
If a resistor of more than 500 k
is connected across input pin and GND, the noise (output) caused by amp 1 and amp 2 select is
liable to increase at the time of F/R switching.
