TDA7498

TDA7498 Datasheet 100-watt + 100-watt dual BTL class-D audio amplifier PowerSSO-36 exposed pad up Features 100 W + 100 W output power at THD = 10% with RL = 6 Ω and VCC = 36 V 80 W + 80 W output power at THD = 10% with RL = 8 Ω and VCC = 34 V Wide-range single-supply operation (14 - 39 V) High efficiency (η = 90%) Four selectable, fixed gain settings of nominally 25.6 dB, 31.6 dB, 35.1 dB and 37.6 dB Differential inputs minimize common-mode noise Standby and mute features Short-circuit protection Thermal overload protection Externally synchronizable Description The TDA7498 is a dual BTL class-D audio amplifier with single power supply designed for home systems and active speaker applications. It comes in a 36-pin PowerSSO package with exposed pad up (EPU) to facilitate mounting a separate heatsink.
