This TDA7294 100 watt power amplifier is designed using few external parts.
TDA7294is manufactured in a multiwatt package with 15 pins intended for use as audio class AB amplifier in Hi-Fi field applications (Home Stereo, self powered loudspeakers, Topclass TV) and offer a short circuit protection add overload thermal protection which is activated at 145 Celsius degree.
TDA7294 100 watt power amplifier circuit offer the stand-by and mutting functions.
Thanks to a wide voltage range and high capability of output current this monolithic integrated circuit can give the maximum power for a 4 ohms impedance or 8 ohms impedance.
This circuit must be mounted on a heatsink ,but must be isolated form ground to prevent a short circuit between ground and negative voltage.
