FUNCTIONAL DESCRIPTION
The TDA8541(T) is a BTL audio power amplifier capable
of delivering 1 W output power to an 8
load at
THD = 10% using a 5 V power supply. 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.
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. The total voltage loss is <1 V and with a 5 V
supply voltage and an 8
loudspeaker an output power of
1 W can be delivered.
Mode select pin
The device is in standby mode (with a very low current
consumption) if the voltage at the MODE pin is
>(V
CC
0.5 V), or if this pin is floating. At a MODE voltage
level of less than 0.5 V the amplifier is fully operational.
In the range between 1.5 V and V
CC
1.5 V the amplifier
is in mute condition. The mute condition is useful to
suppress plop noise at the output, caused by charging of
the input capacitor.
