TDA7492 50 W + 50 W dual BTL class-D amplifier Datasheet - production data Description 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 R = 6 and V = 25 V L CC 40 W + 40 W continuous output power at THD = 10% with R = 8 and V = 25 V L CC Wide-range single-supply operation (8 - 26 V) High efficiency ( = 90%) Four selectable, fixed gain settings of nominally 21.6 dB, 27.6 dB, 31.1 dB and 33.6 dB Differential inputs minimize common-mode noise Standby and mute features Short-circuit protection Thermal overload protection Externally synchronizable ECOPACK , environmentally friendly package Table 1.
