TDA7498 Datasheet PDF - ST Microelectronics

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) tofacilitate mounting a separate heatsink.

●Features

●■ 100-W + 100-W output power at THD = 10% with RL= 6 Ωand 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
