Voltage gain settings (Pins 1 and 8) The voltage gain of the power amplifier is fixed by the internal resistors. • Pins 1 and 8 be left open : Approximately 26dB • Pins 1 and 8 connected to GND : Approximately 39.5dB Note that the voltage gain can be changed using two resistors. (See Fig. 1) • Voltage gain setting : According to the resistor connected between Pin 8 and Pin 2 (GND1) * Voltage gain = 20log (20 × (625 + Rvg1)/(125 + Rvg1)) • Output DC voltage setting : According to the resistor connected between Pin 1 and Pin 2 (GND1) * Rvg1 = Rvg2 must be satisfied. In addition, the voltage gain can also be lowered to approximately 20dB (when using 5V or 6V power supply) by an application such as shown in Fig. 2 below. • Voltage gain setting : According to the resistor connected between Pin 8 and Pin 5 (OUT) * Voltage gain = 20log (20 × (125 + Rvg3)/(10,125 + Rvg3)) • Output DC voltage setting : According to the resistor connected between Pin 1 and Pin 6 (VCC) * Set the resistor values so that the Pin 5 (OUT) DC voltage is approximately half the supply voltage. Example : When Rvg3 = 10kΩ, Rvg4 = 22kΩ (when VCC = 6V) However, note that using this method to greatly lower the voltage gain deteriorates the characteristics, so the voltage gain should be lowered only to approximately 20dB. In addition, when using a high supply voltage (7V or more), the clipped waveform may invert, so this voltage gain reduction method must not be used in these cases.

Signal source impedance : rg The signal source impedance value rg affects the ripple rejection ratio together with input coupling capacitor Cin, so rg should be as small as possible. Therefore, when attenuating the signal at the Cin front end as shown in Fig. 4, the constants should be set in consideration of these characteristics. Using the smallest resistor Rg1 value possible is recommended. In addition, when setting the signal level, the voltage gain should be set on the LA4815M side and the input front-end should be configured using only the input coupling capacitor, Cin, as shown in Fig. 5 in order to maximize the ripple rejection ratio.

Mute control pin (Pin 7) The internal power amplifier circuit can be disabled and audio mute is turned on by controlling the voltage applied to Pin 7. Control can be performed directly using the CPU output port, but digital noise from the CPU may worsen the LA4815M noise floor. Therefore, inserting a series resistor, Rm1 (1 to 2.2kΩ) as shown in Fig. 6, is recommended. • Mute ON : Low • Mute OFF : High or open In addition, the Pin 7 DC voltage is dependent on the supply voltage, so a reverse current flows to the CPU power supply line when the Pin 7 voltage is higher than the CPU supply voltage. In these cases, connect a resistor, Rm2 (see Fig. 7) between Pin 7 and GND to lower the Pin 7 DC voltage as shown in Fig. 6. Note that when not using the mute function, Pin 7 must be left open.

Popping noise reduction during power-off The power supply line can be directly controlled ON and OFF without using the mute function. However, when using a high supply voltage, the shock noise and aftersound during power-off tends to worsen. One method of coping with this is to connect a capacitor between Pin 6 (VCC) and Pin 7 (MUTE) as shown in Fig. 9 so that the auto mute function operates during power-off. Recommended value = 1μF LA4815M 6 VCC + Cmt + 1μF 7 MUTE CVCC Figure 9 6. Input coupling capacitor (Cin) Cin is an input coupling capacitor, and is used for DC cutting. However, this capacitor is also used to improve the ripple rejection ratio, which changes according to the capacitance value (recommended value = 1μF). In addition, this capacitor also affects the transient response characteristics during power-on and when mute is canceled, so the constant should be set in consideration of these characteristics. Design reference value = approximately 0.33 to 3.3μF • Ripple rejection ratio : Increasing the capacitance value increases the rate, and reducing the value reduces the rate. • Rise response speed : Increasing the capacitance value reduces the speed, and reducing the value increases the speed. • Popping noise : Increasing the capacitance value reduces the noise, and reducing the value increases the noise. 7. Output coupling capacitor (Cout) Cout is an output coupling capacitor used for DC cutting. However, this capacitor, Cout, in combination with load impedance RL forms a high-pass filter and attenuates the low frequency signal. Take into account the cutoff frequency when determining the capacitance value. In addition, normally a chemical capacitor is used for this capacitor, but the capacitance value of chemical capacitors decreases at low temperatures, so the value should be set in accordance with this characteristic. The cutoff frequency is expressed by the following formula. fc = 1/(2π × RL × Cout) 8. Output phase compensation capacitor (Cosc) The Cosc capacitor is used to prevent output oscillation. Use a ceramic capacitor (recommended value = 0.1μF) with good high frequency characteristics, and locate this capacitor as close to the IC as possible. 9. Power supply capacitor (CVCC) The CVCC capacitor is used to suppress the ripple component of the power supply line. Normally a chemical capacitor (recommended value = 10μF) is used for this capacitor. However, chemical capacitors have poor high frequency characteristics, so when using a CPU, DSP or other IC that generates digital noise in the set, it is recommended that a power supply bypass capacitor (ceramic capacitor, recommended value = approximately 0.1μF) be added to reject high-frequency components. Locate this bypass capacitor as close to the IC as possible. No.A1373-8/14 LA4815M 10. Signal mixing methods The following methods can be used to mix a beep, key tone or other signal into the audio signal.

Short-circuit between pins Turning on the power supply with some pins short-circuited may cause deterioration or breakdown. Therefore, when mounting the IC on a board, check to make sure that no short-circuit is formed between pins by solder or other foreign substances before turning on the power supply. 12. Load short circuit Leaving the IC for a long time in the condition with a load short circuit may cause deterioration or breakdown. Therefore, never short-circuit the load. 13. Maximum ratings When used under conditions near the maximum ratings, even a slight fluctuation in the conditions may cause the maximum ratings to be exceeded, possibly resulting in a breakdown or other accidents. Therefore, always provide enough margin for fluctuations in the supply voltage and other conditions, and use within a range not exceeding the maximum ratings.
