ST makes class AB audio the prime choice with a new digital input power amplifier
The TDA7802 is the first automotive-qualified, start-stop compliant, analog power amplifier with digital input. It combines the simplicity and cost effectiveness of class AB amplifiers with the sound quality of a digital stream and an efficiency previously unattainable by analog amplifiers. Compared to standard class AB amplifiers, it reduces power dissipation by up to 50%, meeting the standards of car makers for start-stop systems and hybrid vehicles. The TDA7802 is a 4-channel power amplifier with integrated diagnostic features.
