TDA7294

100V - 100W DMOS AUDIO AMPLIFIER WITH MUTE/ST-BY

VERY HIGH OPERATING VOLTAGE RANGE

(±40V)

MULTIPOWER BCD TECHNOLOGY

DMOS POWER STAGE

HIGH OUTPUT POWER (UP TO 100W MU-

SIC POWER)

MUTING/STAND-BY FUNCTIONS

NO SWITCH ON/OFF NOISE

NO BOUCHEROT CELLS

VERY LOW DISTORTION

Multiwatt15

ORDERING NUMBER: TDA7294V

VERY LOW NOISE

SHORT CIRCUIT PROTECTION

THERMAL SHUTDOWN

to the high out current capability it is able to sup-

ply the highest power into both 4Ω and 8Ω 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.

DESCRIPTION

The TDA7294 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
