Part number : TDA7293, TDA7293V
Function : 120V – 100W DMOS AUDIO AMPLIFIER WITH MUTE/ST-BY
Manufacturer : ST Microelectronics
The TDA7293 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 4W and 8W loads. The built in muting function with turn on delay simplifies the remote operation avoiding switching on-off noises.
Parallel mode is made possible by connecting more device through of pin11. High output power can be delivered to very low impedance loads, so optimizing the thermal dissipation of the system.
