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.
