Notes on Using the IC
1. Voltage gain settings (Pins 4 and 11)
The voltage gain of the power amplifier is fixed by the internal resistors.
• Pins 4 and 11 be left open : Approximately 26dB
• Pins 4 and 11 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 4 and Pin 12 (GND1)
* Voltage gain = 20log (20 × (625 + Rvg1)/(125 + Rvg1))
• Output DC voltage setting : According to the resistor connected between Pin 11 and Pin 12 (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 4 and Pin 1 (OUT)
* Voltage gain = 20log (20 × (125 + Rvg3)/(10,125 + Rvg3))
• Output DC voltage setting : According to the resistor connected between Pin 11 and Pin 2 (V
)
CC
* 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 V = 6V)
CC
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.

2. Signal source impedance : rg
Figure 2
As mentioned above, since the input coupling capacitor Cin affects the ripple rejection ratio, the signal source
impedance value rg, which is associated with this capacitor, also affects the ripple rejection ratio, 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 LA4815VH 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.

3. Mute control pin (Pin 3)
The internal power amplifier circuit can be disabled and audio mute is turned on by controlling the voltage applied to
Pin 3. Control can be performed directly using the CPU output port, but digital noise from the CPU may worsen the
LA4815VH 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 3 DC voltage is dependent on the supply voltage, so a reverse current flows to the CPU power
supply line when the Pin 3 voltage is higher than the CPU supply voltage. In these cases, connect a resistor, Rm2 (see
Fig. 7) between Pin 3 and GND to lower the Pin 3 DC voltage as shown in Fig. 6.
Note that when not using the mute function, Pin 3 must be left open.

5. 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 2 (V ) and Pin 3 (MUTE) so that the auto mute function operates during
CC
power-off.

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 signals. 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 × R × Cout)
L
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 (CV
)
CC
capacitor is used to suppress the ripple component of the power supply line. Normally a chemical capacitor
The CV
CC
(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.
10. NC pin treatment
Since the NC pins (pins 5 to 10) are connected to nothing internally, they may be left open. To increase the heat
dissipation efficiency, however, it is recommended that the NC pins should be connected to the GND line.

11. Signal mixing methods
The following methods can be used to mix a beep, key tone or other signal into the audio signal. Note that when input
to Pin 4 is selected, amplification of signals input from Pin 4 changes according to impedance Z4 connected to Pin 13.

12. 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.
13. 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.
14. 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.
