TDA7262 audio power amplifier

With this chip manufactured by STMicroelectronics we can make an dual power amplifier with a power above 20 W ( 20 +20 W).
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.
TDA7262 have an BUILD-IN PROTECTION SYSTEMS like :
Thermal shut-down for protection of high temperature ( an overload on the output or an excessive ambient temperature ) .
Short circuit (AC Conditions) for the accidental shortcircuit across the speakers .
The TDA7262 multiwatt package must be mounteo on an external heatsink .
Between the heatsink and the TDA7262 package it is better to insert a layer of silicon grease, to optimize the thermal contact.
Between Tda7262 and package no electrical isolation is needed .
