TDA7492 Amplifier Description


The TDA7492 is a dual BTL class-D audio amplifier with a single power supply that is intended for use in LCD TVs and monitors. Only a minimal heatsink is required due to the high efficiency and exposed-pad-up (EPU) packaging. Overvoltages, undervoltages, overcurrents, and thermal overloads are all adequately protected by the TDA7492.
