TDA7491P

10W+10W dual BTL class-D audio amplifier
  • active 活性

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.
