However, the input coupling capacitor C1 (C2) and input resistor R1 (R2) make up the high-pass filter, attenuating the bass frequency. Therefore, the capacitance value must be selected with due consideration of the cut-off frequency. The cut-off frequency is expressed by the following formula : fc = 1/2 π × R1 × C1 (= 1/2 π × R2 × C2) Note with care that this capacitance value affects the pop noise at startup. To increase this capacitance value, it is necessary to increase the capacitance value of pin 7 capacitor (C5) to soften the startup characteristics. 2.Pin 7 capacitor (C5) This capacitor C5 is designed for the ripple filter. Its purpose is to make up a low-pass filter with a 100kΩ internal resistor for reducing the ripple component of the power supply and improve the ripple rejection ratio. Inside the IC, the startup characteristics of the pin 7 voltage are used to drive the automatic pop noise reduction circuit, and care must be taken with the pop noise when the C5 capacitance value is to be set lower. However, when the IC is used in BTL mode, the automatic pop noise reduction function mentioned above has no effect. Instead, a pop noise reduction method that utilizes the second amplifier control function is used so that the capacitance value must be determined while factoring in the ripple rejection ratio or startup time. Recommended capacitance value : Min. 22μF (in 2-channel mode) 10μF (in mono BTL mode) 3.Bypass capacitor (C7) The purpose of the bypass capacitor C7 is to reject the high-frequency components that cannot be rejected by the power supply capacitor (chemical capacitor C6). Place the capacitor as near to the IC as possible, and use a ceramic capacitor with excellent high-frequency characteristics. 4.Standby function The standby function serves to place the IC in standby mode to minimize the current drain. a) When using the standby function (when using microcomputer control) By applying the following voltages to the standby pin (pin 8), the mode changeover can be performed between standby and operation. Operation mode … V8 ≥ 1.6V Standby mode … V8 ≤ 0.3V However, set the resistance of resistor R5 inserted in series in such a way that the condition in the following formula is met. R5 ≤ 24.6 × (Vstby - 1.6) kΩ R5 The pin 8 inrush current is expressed by the following formula: 8 STBY Vstby V8 I8 = (40 × Vstby - 26.3)/(1+0.04 × R5) μA Fig. 1 b) When not using the standby function (microcomputer control is not possible) By applying a voltage from the power supply (pin 14) to the standby pin (pin 8), the IC can be turned on without the control of the microcomputer when the power is turned on. In order to reduce the pop noise when the IC is turned off, it is recommended that resistor R5 be inserted as shown in Fig.2. The resistance value indicated below is recommended for the inserted resistor R5. VCC = 5.0V : R5 = 82kΩ VCC = 3.6V : R5 = 47kΩ VCC = 3.0V : R5 = 33kΩ VCC 14 VCC R5 8 STBY Fig. 2 No.A0972-5/17 LA4814V 5.Second amplifier control function (only when BTL mode is used) The second amplifier control function is a function to reduce the startup pop-noise in BTL mode. The pop noise can be reduced by first turning on the IC while the second amplifier is stopped, then after the potential inside the IC gets stabilized, turning on the second amplifier. The values shown below are recommended for the control time.

Second amplifier operation mode … V9 ≤ 0.3V Second amplifier stop mode … V9 ≥ 1.6V However, set the resistance value of the resistor R6 inserted in series in such a way that the condition in the following formula is met. R6 ≤ 16.2 × (Vcnt - 1.6) kΩ R6 The pin 9 injected current is expressed by the following formula : 9 CNT Vcnt I9 = (57.6 × Vcnt - 31.7)/(1+0.058 × R6) μA V9 Fig. 3 b) When microcomputer control is not possible When the microcomputer cannot be used, the second amplifier can be controlled by adding the external components as shown in Fig. 4.

Therefore, check before power application if pins are short-circuited with solder, etc. during mounting of IC. 7.Load shorting If the load is left short-circuited for a long period of time, electrical deterioration or damage may occur. Never allow the load to short-circuit. 8.Maximum rating When IC is used near the maximum rating, there is a possibility that the maximum rating may be exceeded even under the smallest change of conditions, resulting in failure. Take sufficient margin for variation of supply voltage and use IC within a range where the maximum rating will never be exceeded. No.A0972-6/17 LA4814V 9.Turn-off transient response characteristics If the IC is turned off and then turned back on while there is a potential difference between the pin 7 (reference voltage, plus input pin) and pins 5 and 10 (minus input pins), a louder pop noise than the one normally generated when power is switched on will be emitted. Therefore, in order to minimize the turn-on pop noise, smoothen the discharge of the input and output capacitors, and bring the potential of pin 7 and pins 5 and 10 to approximately the same level, then turn on the IC. a) Single ended mode When the continuous changeover of mode between standby and operation is necessary, it is recommended to insert a resistor between the output pins (pins 3 and 12) and ground to accelerate the turn-off transient response characteristic. The value shown below is recommended for the resistor used for discharge. In order to reduce pop noise, it is recommended that time necessary for turning the IC back on is greater than the following value. Recommended discharge resistor : R = 4.7kΩ (Recommended turn-on time : T = 600ms) 4.7kΩ + RL 4Ω OUT:50mV/div,AC 100ms/div 7pin:1V/div,DC 3 OUT1 R3 33kΩ STBY→PWR C3 470μF PWR→STBY + - Vref 10kΩ 5 IN1 R1 10kΩ C1 0.22μF T b) BTL mode When the continuous changeover of mode between standby and operation is performed, it is recommended that the second amplifier control function be used to reduce the turn-on pop noise. If this function is used, the pop noise level can be reduced regardless of the time taken for the IC to turn on after it is turned off. For details on the time taken for the second amplifier to turn on after the IC is turned on, refer to Section 5 “Second amplifier control function.” No.A0972-7/17 LA4814V + R5 10kΩ C4 470μF C2 0.22μF R2 10kΩ R4 33kΩ 12 11 10 9 8 1 2 3 4 5 6 7 + C3 470μF 13 SPEAKER 4Ω 14 R3 33kΩ + R1 10kΩ C1 0.22μF C5 22μF IN2 SPEAKER 4Ω + C7 0.1μF C6 10μF VCC from CPU Application Circuit Example 1.
