TDA7296 STMicroelectronics

TDA7296 Datasheet 70 V-60 W DMOS audio amplifier with mute/ST-BY Features Multipower BCD technology Very high operating voltage range ( 35 V) DMOS power stage Multiwatt 15 High output power (up to 60 W music power) Muting/standby functions No switch on/off noise No boucherot cells Very low distortion Very low noise Short-circuit protection Thermal shutdown Description The TDA7296 is a monolithic integrated circuit in multiwatt15 package, intended to be used as 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 4 and 8 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 Product status link avoiding switching on/off noises.
