Pin Descriptions
1. Standby switching function (7)
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.
Applied voltage
VBE (approx. 0.7V)
Current supplied

When directly connecting a microcontroller with this pin, add a resistor in
series to optimize the current for the microcontroller.
2. Input pins (8, 10)
Voltage at the input pins is approx. 2VBE (1.4V).
Input impedance is approx. 30k
.
The recommended value for the input capacitor is 0.22F, but this can be varied in order to adjust the starting time (ts).
(The starting time is the time required from applying voltage to the standby pin until sound output is obtained. )
