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.
