Standby switching function (7) VCC 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 To bias circuit µA to pin 7. . Current supplied to pin 7 =. Applied voltage Applied voltage – VBE (approx. 0.7V) + 2 kΩ 2 kΩ 7 2kΩ • When directly connecting a microcontroller with this pin, add a resistor in series 2kΩ to optimize the current for the microcontroller. 2. Input pins (8,10) Voltage at the input pins is approx. 2 VBE (1.4V). Input impedance is approx. 30 kΩ. • 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. ) Input capacitator 1.0 µF 2.0 µF 3.3 µF 4.7 µF 10 µF Starting time (ts) 0.2s 0.3s 0.5s 0.65s 1.5s 3. Filter (decoupling) pin (5) Pin voltage is approx. 1/2 VCC. 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. Filter capacitor= 100 µ AC voltage (100 mV) Output DC voltage Filter capacitor= 47 µF AC voltage (200mV) Output DC voltage No. 6012-4/7 LA4600 4. P.P (pop noise) pin (6) VCC . VCC – VCE (approx. 0.3V) – 5.6V Voltage at pin 6 =. 2 + 5.6V • The recommended value for the P.P capacitor is 4.7 µF. When capacitance is lower than 2.2 µF, pop noise when setting the standby pin to Low (power OFF) will increase. 5kΩ 6 5kΩ When capacitance is higher than 10 µF, the sound will not be cut off when setting the standby pin to Low (power OFF). Zener voltage = 5.6V To input amplifier/ bias circuitry 5. Muting The output signal can be controlled by connecting pin 5 (Filter) to ground via a resistance of 300 to 500 Ω. If resistance is higher than 750 Ω, the suppression Output AC voltage Output DC voltage ratio will decrease.
