TDA7492 - ST Microelectronics

TDA7492 50W + 50W dual BTL class-D audio amplifier

The TDA7492 is a dual BTL class-D audio amplifier with single power supply designed for LCD TVs and monitors. Thanks to the high efficiency and exposed-pad-up (EPU) package, only a simple heatsink is required. PowerSSO-36 with exposed pad up Features  50 W + 50 W continuous output power at THD = 10% with RL = 6  and VCC = 25 V  40 W + 40 W continuous o.
