LA4613 Pin Descriptions 1. Standby switching function (9)
Power is switched ON and OFF by controlling the High and Low states at pin 9, respectively (standby). To switch power ON, apply 1.5V or more, or 800 A to pin 9. . Applied voltage Applied voltage - VBE (approx. 0.7V) + Current supplied to pin 9 = . 2 k 2 k
9 2k To bias circuit VCC
* When directly connecting the microcontroller with this pin, add a resistor in series to optimize the current for the microcontroller.

2. Input pins (11,13)
Voltage at the input pins is approx. 2 VBE (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 (ts). (The starting time is the time required from applying voltage to the standby pin until sound output is obtained.)

3. Filter (decoupling) pin (7)
Pin voltage is approx. 1/2 VCC. 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.

VCC - VCE (approx. 0.3V) - 5.6V Voltage at pin 8 . . + 5.6V = 2 * 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).

5. Muting
The output signal can be controlled by connecting pin 7 (Filter) to ground via a resistance of 300 to 500 . If resistance is higher than 750 , the suppression ratio will decrease.
