TDA8547 Description
APPLICATIONS Telemunication equipment Portable consumer products Personal puters Motor-driver (servo). TDA8547 The TDA8547(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 plementary PNP-NPN output stage and standby/mute logic.
