TDA7294

TDA7294 Datasheet 100 V, 100 W DMOS audio amplifier with mute/st-by MULTIPOWER BCD TECHNOLOGY Multiwatt15V Multiwatt15H Maturity status link TDA7294 Order code TDA7294V TDA7294HS Package Multiwatt15V Multiwatt15H Features Very high operating voltage range (± 40 V) DMOS power stage High output power (up to 100 W music power) Muting/stand-by functions No switch on/off noise No boucherot cells Very low distortion Very low noise Short circuit protection Thermal shutdown Description The TDA7294 is a monolithic integrated circuit in Multiwatt15 package, intended for use as audio class AB amplifier in Hi-Fi field applications (Home Stereo, self powered loudspeakers, Topclass TV). Thanks to the wide voltage range and to the high out current capability it is able to supply the highest power into both 4 Ω and 8 Ω 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.
