产品概述
描述
The TDA7491P 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 component count.
The TDA7491P is pin-to-pin compatible with the TDA7491LP and TDA7491HV.
