Product overview
Description
The TDA7491MV is a mono BTL class-D audio amplifier with single power supply designed for LCD TVs and monitors.
Thanks to the high efficiency and an exposed-pad-down (EPD) package no heatsink is required.
Furthermore, the filterless operation allows a reduction in the external component count.
The TDA7491MV is pin to pin compatible with the TDA7491P, TDA7491LP and TDA7491HV for the left channel.
