1. Standby switching function
Power is switched ON and OFF by controlling the High and Low states at pin 7,
respectively (standby). To switch power ON, apply 1.5V or more, or 800
A to
pin 7.
When directly connecting the microcontroller, add a resistor in series
to optimize the current for the microcontroller.
2. Input pins (8,10)
Voltage at the input pins is approx. 2 V
BE
(1.4V).
Input impedance is approx. 30 k
.
The recommended value for the input capacitor is 0.22
F, but this can be varied in order to adjust the starting time
(t
s
). (The starting time is the time required from applying voltage to the standby pin until sound output is obtained.)
3. Filter (decoupling) pin (5)
Pin voltage is approx. 1/2 V
CC
.
The recommended value for the filter capacitor is 100
F.
When capacitance is lower, pop noise when setting the standby pin to Low (power OFF) will increase.

4. P.P (pop noise) pin (6)
5. Muting
The recommended value for the P.P capacitor is 4.7
F. When capacitance is
lower than 2.2
F, pop noise when setting the standby pin to Low (power
OFF) will increase.
When capacitance is higher than 10
F, the sound will not be cut off when
setting the standby pin to Low (power OFF).
The output signal can be controlled by
connecting pin 5 (Filter) to ground via a
resistance of 300 to 500
. If resistance
is higher than 750
, the suppression
ratio will decrease.
