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
@ THD =10%, with VS = ±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)
Description
The TDA7293 is a monolithic integrated circuit in
Multiwatt15 package, intended for use as audio
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-
and 8-
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
