The TDA7294 is a monolithic integrated circuit in the Multiwatt15 package, intended for use as an audio class AB amplifier in Hi-Fi field applications (Home Stereo, self-powered loudspeakers, Top class TV). Thanks to the wide voltage range and to the high out current capability it is able to supply the highest power into both 4Ω and 8Ω loads even in presence of poor supply regulation, with high Supply Voltage Rejection. The built-in muting function with turn-on delay simplifies the remote operation avoiding switching on-off noises.
