TDA7492P 25 W + 25 W dual BTL class-D audio amplifier Datasheet - production data Description The TDA7492P 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- down (EPD) package no heatsink is required. PowerSSO-36 with exposed pad down Features 25 W + 25 W continuous output power at THD = 10% with V = 20 V and R = 8 CC L 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.
