The inflowing current at an
applied voltage of 1.5V, i.e.
the point when the amplifier
turns on, is approximately
750
A.
STBY pin applied voltage : 5V
To hold the pin 1 inflow current to about 750
A insert a resistor (Rx) of 4.7k
STBY pin applied voltage : 12V
To hold the pin 1 inflow current to about 750
A insert a resistor (Rx) of 14k (12k).
STBY pin applied voltage : Other value (Vx)
To hold the pin 1 inflow current to about 750
A insert a resistor (Rx) of (Vx 1.5V)/750A.
If a microcontroller output signal is applied directly, insert a resistor in series and adjust the current to a level
optimal for the drive capability of the microcontroller.
2. Input pins (pins 6 and 7)
The input pin voltage is about 2VBE (1.4V).
The input pin impedance is about 30k
.
Although the recommended value for the input capacitor is 0.22F, the starting time can be modified by changing
the value of this capacitor. (The time from the point a voltage is applied to the standby pin to the point sound is
emitted.)
