Description
The TDA7491HV is a dual BTL class-D audio amplifier with single power supply designed for LCD TVs and monitors. Thanks to the high efficiency and slug-down package no heatsink is required. Furthermore, the filterless operation allows a reduction in the external component count. The TDA7491HV is pin to pin compatible with the TDA7491P and TDA7491LP.
