DESCRIPTION

The TDA7298 is a monolithic integrated circuit in

Heptawatt package, intended for use as audio

class AB amplifier in TV or Hi-Fi field application.

Thanks to the wide voltage range and to the high

out current capability it’s able to supply the high-

est power into both 4

Ω and 8Ω loads even in

presence of poor supply regulation.

The built in Muting/Stand-by function simplifies

the remote operations avoiding also switching on-

off noises.
