About the Item
ST TDA7293 120V 100W DMOS Audio Amplifier with MUTE/ST-BY
– VERY HIGH OPERATING VOLTAGE RANGE (+/-50V)
– DMOS POWER STAGE
– HIGH OUTPUT POWER (100W @ THD = 10%, RL = 8Ohms, VS = +/-40V)
– MUTING/STAND-BY FUNCTIONS
– NO SWITCH ON/OFF NOISE
– VERY LOW DISTORTION
– VERY LOW NOISE
– SHORT CIRCUIT PROTECTION
– THERMAL SHUTDOWN
– CLIP DETECTOR
– MODULARITY (MORE DEVICES CAN BE EASILY CONNECTED IN PARALLEL TO DRIVE VERY LOW IMPEDANCES)
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, 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 Ohm and 8 Ohm 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.
