FUNCTIONAL DESCRIPTION
The TDA8543(T) is a BTL audio power amplifier capable
of delivering an output power between 1 and 2 W,
depending on supply voltage, load resistance
and package. Using the MODE pin the device can
be switched to standby and mute condition. The device
is protected by an internal thermal shutdown protection
mechanism.
The gain can be set within a range from 6 dB to 30 dB
by external feedback resistors.
Power amplifier
The power amplifier is a Bridge Tied Load (BTL) amplifier
with a complementary PNP-NPN output stage.
LIMITING VALUES
In accordance with the Absolute Maximum Rating System (IEC 134).
QUALITY SPECIFICATION
In accordance with “SNW-FQ-611-E”. The number of the quality specification can be found in the “Quality Reference
Handbook”. The handbook can be ordered using the code 9397 750 00192.

The voltage loss on the positive supply line is
the saturation voltage of a PNP power transistor,
on the negative side the saturation voltage of an
NPN power transistor.
Mode select pin
The device is in standby mode (with a very low current
consumption) if the voltage at the MODE
pin is >(V
voltage level of less than 0.5 V the amplifier is fully
operational.
In the range between 1.5 V and V
is in mute condition. The mute condition is useful to
suppress plop noise at the output, caused by charging of
the input capacitor.
