15 − GENERAL DESCRIPTION TDA8542TS The TDA8542TS is a two channel audio power amplifier for an output power of 2 × 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.
APPLICATIONS • Portable consumer products • Personal computers • Motor-driver (servo).
