Part Details:

TDA7493 2.8 W + 2.8 W dual BTL class-D audio amplifier Features ! 2.8 W + 2.8 W continuous output power RL = 4 , THD = 10%, Vcc = 5 V ! Single supply voltage range 3 V to 5.5 V ! High efficiency ( = 83%) ! Four selectable, fixed gain settings of 6 dB, 12 dB, 15.6 dB and 18 dB HTSSOP24 exposed pad down ! Differential inputs minimize common-mode noise Description ! Filterless operation ! Stand-by feature The TDA7493 is a dual BTL class-D audio amplifier, specially designed for LCD TV, LCD ! Short-circuit protection monitors or small speakers on cradles with ! Thermal-overload protection single-supply operation. ! Externally synchronizable. The filterless operation allows the external components count to be reduced. The TDA7493 is assembled in the HTSSOP24 package. Thanks to the high-efficiency, slug-down package no separate heatsink is required. Table 1.
