TDA7293 120-volt, 100-watt, DMOS audio amplifier with mute and standby Features Multipower BCD technology Very high operating voltage range (±50 V) DMOS power stage High output power (100 W into 8 Ω @ THD =10%, with VS = ±40 V) Muting and stand-by functions No switch on/off noise Very low distortion Very low noise Short-circuit protected (with no input signal applied) Thermal shutdown Clip detector Modularity (several devices can easily be connected in parallel to drive very low impedances)
The TDA7293 is a monolithic integrated circuit in Multiwatt15 package, intended for use as audio Multiwatt15V Multiwatt15H class AB amplifier in Hi-Fi field applications, such as home stereo, self powered loudspeakers and Topclass TV. Thanks to the wide voltage range and to the high output current capability it is able to supply the highest power into both 4-Ω and 8-Ω loads. The built-in muting function with turn-on delay simplifies the re [ … ]
