TDA7293HS STMicroelectronics

TDA7293 120-volt, 100-watt, DMOS audio amplifier with mute and standby Features Multipower BCD technology Very high operating voltage range (50 V) Multiwatt15V DMOS power stage Multiwatt15H High output power (100 W into 8 class AB amplifier in Hi-Fi field applications, such THD =10%, with V = 40 V) S as home stereo, self powered loudspeakers and Muting and stand-by functions Topclass TV. Thanks to the wide voltage range and to the high output current capability it is able No switch on/off noise to supply the highest power into both 4- and 8- Very low distortion loads. Very low noise The built-in muting function with turn-on delay Short-circuit protected (with no input signal simplifies the remote operation avoiding on-off applied) switching noises. Thermal shutdown Parallel mode is possible by connecting several Clip detector devices and using pin11. High output power can be delivered to very low impedance loads, so Modularity (several devices can easily be optimizing the thermal dissipation of the system connected in parallel to drive very low impedances) Table 1.
