* LA42101 employs the zero-bias type input circuit, with the input pin potential being nearly zero (about 0.01V).
Accordingly, the polarity must be determined according to the DC potential of a circuit connected to the previous stage
of LA42101.

External Components
C1
: The input coupling capacitors, for which 4.7μF or less is recommended. LA42101 employs the zero-bias type
input circuit, with the input pin potential being nearly zero (about 0.01V). Accordingly, the polarity must be
determined according to the DC potential of a circuit connected to the previous stage of LA42101.
: Capacitor for starting time of the ripple filter and amplifier, for which 47μF is recommended.
C2
C3, R1 : Capacitor and resistor for mute. C3 is necessary even when the mute function is not used.
C4 : Power capacitor.
C5, C6 : Capacitor and resistor for oscillation prevention. For C5, C6, the polyester film capacitor with superior
R2, R3 temperature characteristics (Mylar capacitor) is recommended. Use R2, R3 of 2.2Ω along with the capacitor.
1. Mute function (pin 6)
With the pin 6 voltage of 1.5V (minimum) or more, the mute function is turned ON.
Set the V application voltage so that the pin 6 voltage becomes. 1.5V or more.
M
The mute time constant is determined by R1 and C3. Determine the constant after careful review because it is related
to the pop sound at mute ON/OFF.
C4 is necessary even when the mute function is not used because it is related to the pop sound when the amplifier is
turned ON.
Example : The pin 6 voltage becomes about 1.8V when V = 5V and R1 = 15kΩ.
M
Mute
Note that the MUTE pin (pin 6) incorporates the anti-static
diodo and that decrease of the V
pin 7 potential below that of
CC
pin 6 causes the current to flow through the diode.

Cautions for us
1. Short-circuit (power-output short-circuit), ground fault (GND-output short-circuit), and load short-circuit protective
circuits are incorporated. They are activated in case of abnormal connection.
These circuits remain active while such abnormal connection continues and is reset automatically when the
abnormality is removed.
In certain conditions, the protective circuits may be locked and continue to be active even when the abnormality is
removed. In this case, either enter the standby mode or turn OFF the power supply.
2. The thermal protection circuit is incorporated and is activated when the junction temperature (Tj) rises to about 160°C
or more. The output is controlled to return gradually to the attenuated state.
3. When the product is used near the maximum rating, even the slightest change in the condition may cause exceeding of
the maximum rating, resulting possibly in breakdown. Take the sufficient margin for the supply voltage, etc. and
always use the product within a range never exceeding the maximum rating.
