Cautions for Use
1.
Input coupling capacitors (C1, C2)
C1 and C2 are input coupling capacitors that are used to cut DC voltage. 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 10 capacitor (C5) to soften the startup characteristics.
2.
Pin 10 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 10 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 11), the mode changeover can be performed between
standby and operation.
Operation mode … V11 ≥ 1.6V
Standby mode … V11 ≤ 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 11 inrush current is expressed by the following formula:
11 STBY
Vstby
I11 = (40 × Vstby - 26.3)/(1+0.04 × R5) μA
V11
Fig. 1
b) When not using the standby function (microcomputer control is not possible)
By applying a voltage from the power supply (pin 17) to the standby pin (pin 11), 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

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.

a) When using microcomputer control
The second amplifier can be controlled by applying the following voltages to pin 12.
Second amplifier operation mode … V12 ≤ 0.3V
Second amplifier stop mode … V12 ≥ 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 12 injected current is expressed by the following formula :

I12 = (57.6 × Vcnt - 31.7)/(1+0.058 × R6) μA

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.

6.Shorting between pins
When power is applied with pins left short-circuited, electrical deterioration or damage may result.
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.A2040-8/16
LA4814JA
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 10 (reference voltage,
plus input pin) and pins 8 and 15 (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 10 and pins 8 and 15 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 6 and 15) 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)

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.”
