TDA8543 - NXP

TDA8543 2 W BTL audio amplifier

TDA8543 The TDA8543(T) is a one channel audio power amplifier for an output power of 2 W with an 8 Ω 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.
