The TDA8542TS is a two channel audio power amplifier for an output power of 2 x 0.7 W with
a 16 Ω load at a 5 V supply. 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.
