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 V

= ±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)

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 remote operation avoiding on-off

switching noises.

Parallel mode is possible by connecting several

devices and using pin11. High output power can

be delivered to very low impedance loads, so

optimizing the thermal dissipation of the system
