Product overview
Description
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 component count.
The TDA7491LP is pin-to-pin compatible with the TDA7491P and TDA7491HV.
