FUNCTIONAL DESCRIPTION
The TDA8547TS is a 2 × 0.7 W BTL audio power amplifier
capable of delivering 2 × 0.7 W output power to a 16 Ω
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 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 a NPN power

DESCRIPTION

transistor. The total voltage loss is <1 V and with a 5 V
supply voltage and a 16 Ω loudspeaker an output power of
0.7 W can be delivered, when two channels are operating.
If only one channel is operating then an output power of
1.2 W can be delivered (5 V, 8 Ω).
MODE pin
The whole device (both channels) is in the standby mode
(with a very low current consumption) if the voltage at the
MODE pin is >(V
MODE voltage level of less than 0.5 V the amplifier is fully
operational. In the range between 1.5 V and 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.
