GENERAL DESCRIPTION
The TDA8542(T) is a two channel audio power amplifier
for an output power of 2
×
1 W with an 8
Ω
load at a 5 V
supply. The circuit contains two BTL amplifiers with a
complementary PNP-NPN output stage and standby/mute
logic. The TDA8542T comes in a 16 pin SO package and
the TDA8542 in a 16 pin DIP package.
