GENERAL DESCRIPTION
The TDA8543(T) is a one channel audio power amplifier
for an output power of 2 W with an 8 ? load at a 7.5 V
supply. The circuit contains a BTL amplifier with
a complementary PNP-NPN output stage and
standby/mute logic. The TDA8543T comes in a 16 pin
SO package and the TDA8543 in a 16 pin DIP package.
APPLICATIONS
? Portable consumer products
? Personal computers
? Telephony.
