STMicroelectronics TDA7498E Dual BTL Class-D Audio Amplifier

STMicroelectronics TDA7498E Dual BTL Class-D Audio Amplifier features a single power supply designed for home systems and active speaker applications. Features of the TDA7498E Dual BTL Class-D Audio Amplifier include wide-range single-supply operation, high efficiency, parallel BTL function using the MODE pin, four selectable, fixed gain settings, differential inputs that minimize common-mode noise, standby and mute features, smart protection, and thermal overload protection. The STMicroelectronics TDA7498E Dual BTL Class-D Audio Amplifier comes in a 36-pin PowerSSO package with exposed pad up (EPU) to facilitate mounting a separate heatsink.
