TDA7262 stereo 20 watts audio amplifier circuit design

Using TDA7262 integrated circuit manufactured by ST Microelectronics can be designed a very simple stereo audio amplifier electronic project which can provide a maximum output power of 20 watts per channel .
TDA7262 is an ( class AB ) dual Hi-Fi Audio power amplifier assembled in Multiwatt 11 package, specilally designed for high quality stereo application as Hi-Fi music centers and TV sets.
Between the heatsink and the audio amplifier IC package it is better to insert a layer of silicon grease, to optimize the thermal contact.
Between the audio amplifier IC and package no electrical isolation is needed .
