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

µA to pin 7.

To bias circuit

• 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)

Input impedance is approx. 30 k

Ω.

• The recommended value for the input capacitor is 0.22

µF, 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. )

3. Filter (decoupling) pin (5)

The recommended value for the filter capacitor is 100

µF.

When capacitance is lower, pop noise when setting the standby pin to Low (power OFF) will increase.
