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).

A DMOS (Double-Diffused Metal-Oxide-Semiconductor) audio amplifier is a type of amplifier commonly used in audio applications. DMOS amplifiers are known for their high output power capability, low distortion, and efficient operation.

DMOS amplifiers are often used in audio systems such as stereo amplifiers, home theater systems, and professional audio equipment. They are capable of delivering high-quality audio reproduction with sufficient power output to drive speakers effectively.

Thanks to the wide voltage range and to the high out current capability it is able to supply 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.
