TDA7491LP Overview
The TDA7491LP is a dual BTL class-D audio amplifier with single power supply designed for LCD TVs and monitors. Thanks to the high efficiency and exposed-pad-down (EPD) package no separate heatsink is required. Furthermore, the filterless operation allows a reduction in the external ponent count.
TDA7491LP Key Features
