Standby switch function (pin 6) Rx STBY 2 kΩ 6 + 2 kΩ Applied standby voltage Vx The inflowing current at an applied voltage of 1.5 V, i.e. the point when the amplifier turns on, is approximately 750 µA. ILA00075 STBY pin applied voltage: 5 V To hold the pin 6 inflow current to about 750 µA insert a resistor (Rx) of 4.7 kΩ STBY pin applied voltage: 12 V To hold the pin 6 inflow current to about 750 µA insert a resistor (Rx) of 14 kΩ (12 kΩ). STBY pin applied voltage: Other value (Vx) To hold the pin 6 inflow current to about 750 µA insert a resistor (Rx) of (Vx - 1.5 V)/750 µA. • 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 9 and 10) The input pin voltage is about 2 VBE (1.4 V). The input pin impedance is about 30 kΩ. • Although the recommended value for the input capacitor is 0.22 µF, 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.)

The recommended value for the filter capacitor is 100 µF. The pulse noise that occurs when the standby pin is set low (power off) will be degraded if a value under 100 µF is used. AC voltage (100 mV) AC voltage (200 mV) Output DC voltage Output DC voltage Filter capacitor = 100 µF Filter capacitor = 47 µF ILA00078 ILA00079 VCC 5 kΩ 4. P.P (pulse noise) pin (pin 8) Pin 8 pin voltage ≈ VCC - VCE (about 0.3 V) - 5.6 V + 5.6 V 2 kΩ 8 5 kΩ • The recommended value for the P.P capacitor is 4.7 µF. The pulse noise that occurs when the standby pin is set low (power off) will be degraded if a value under 2.2 µF is used. Furthermore, if a value over 10 µF is used, the signal may not be cut off and sound may remain audible when the standby pin is set low (power off). Zener voltage = 5.6 V To the input amplifier block/bias system ILA00080 5. MUTE (Muting) The output signal can be controlled by shifting the pin 7 (FILTER) level towards ground with a 300 to 500 Ω resistor. However, note that the degree of suppression is reduced if a value of 750 Ω or more is used.
