TDA7492E数据手册ST中文资料规格书

描述 Description

The TDA7492E is a dual BTL class-D audio amplifier with single power supply designed for home audio applications.

The device is housed in a 36-pin PowerSSO package with exposed pad up (EPU), and as a result of its high efficiency, a simple heatsink is required.
