At a low supply voltage of 3.3 V an output power of 0.6 W with an 8 Ω load can be obtained. The circuit contains two Bridge-Tied Load (BTL) amplifiers with a complementary PNP-NPN output stage and standby/mute logic. The TDA8542TS is available in a SSOP20 package. APPLICATIONS • Portable consumer products • Personal computers • Motor-driver (servo). .
