ST’s analog switch-mode class D power amplifiers enable a higher efficiency, thus reducing the power dissipation and the need for larger heatsinks.
The class D portfolio ranges from 2 W up to 2 x 160 W in mono and stereo configurations and offers:
- Filtered and filterless operation
- Externally synchronizable
- Surface-mount PSO and PSSO36 slug-up and -down packages for optimized space
TDA7491P 10W+10W dual BTL class-D audio amplifier
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.
