® 80V - 80W DMOS AUDIO AMPLIFIER WITH MUTE/ST-BY VERY HIGH OPERATING VOLTAGE RANGE (±40V) DMOS POWER STAGE HIGH OUTPUT

TDA7295 TDA7295 ® 80V - 80W DMOS AUDIO AMPLIFIER WITH MUTE/ST-BY VERY HIGH OPERATING VOLTAGE RANGE (±40V) DMOS POWER STAGE HIGH OUTPUT POWER (UP TO 80W MUSIC POWER) MUTING/STAND-BY FUNCTIONS NO SWITCH ON/OFF NOISE NO BOUCHEROT CELLS VERY LOW DISTORTION VERY LOW NOISE SHORT CIRCUIT PROTECTION THERMAL SHUTDOWN DESCRIPTION The TDA7295 TDA7295 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 MULTIPOWER BCD TECHNOLOGY Multiwatt 15 ORDERING NUMBER: TDA7295 TDA7295 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 avoiding switching on-off noises.
