1. Voltage Gain Settings (Pins 4 and 11)
The voltage gain of the power amplifier is fixed by the
internal resistors.

2. Signal Source Impedance: rg
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 Figure 8, 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 Figure 9 in order to maximize the
ripple rejection ratio.

♦ Rvg1 = Rvg2 must be satisfied.
In addition, the voltage gain can also be lowered to
approximately 20 dB (when using 5 V or 6 V power supply)
by an application such as shown in Figure 6 below.

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 20 dB. In
addition, when using a high supply voltage (7 V or more),
the clipped waveform may invert, so this voltage gain
reduction method must not be used in these cases.

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
Figure 11) between Pin 3 and GND to lower the Pin 3 DC
voltage as shown in Figure 10.
Note that when not using the mute function, Pin 3 must be
left open.
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 2.2 kW) as shown in Figure 10, is
recommended.

4. Mute Control Timing
When performing mute control, exercise control at the
timing shown in Figure 12.
• During power−on: Twu = 0 to 50 ms
♦ Pins 2 and 3 can also rise simultaneously.
• During power−off: Twd = 100 to 200 ms
•
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.

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 after sound during
power−off tends to worsen. One method of coping with this
is to connect a capacitor between Pin 2 (VCC) and Pin 3
(MUTE) so that the auto mute function operates during
power−off.

8. Output Phase Compensation Capacitor (Cosc)
The Cosc capacitor is used to prevent output oscillation.
Use a ceramic capacitor (recommended value = 0.1 mF) 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 = 10 mF) 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
0.1 mF) be added to reject high−frequency components.
Locate this bypass capacitor as close to the IC as possible.

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.
Figure 13.
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.
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 = 1 mF). 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 3.3 mF
• Ripple Rejection Ratio: Increasing the capacitance value
increases the rate, and reducing the value reduces the rate.
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.

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.
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.
