GENERAL DESCRIPTION
The TDA8547(T) is a two channel audio power amplifier
for an output power of 2
×
1 W with an 8
load at a 5 V
supply. The circuit contains two BTL amplifiers with a
complementary PNP-NPN output stage and standby/mute
logic. The operating condition of all channels of the device
(standby, mute or on) is externally controlled by the
MODE pin. With the SELECT pin one of the output
channels can be switched in the standby condition. This
feature can be used for loudspeaker selection and also
reduces the quiescent current consumption.
The TDA8547T comes in a SO16 package and the
TDA8547 in a DIP16 package.
