意法半导体的模拟开关模式D类功率放大器提高了效率，从而降低了功耗和对大散热器的需要。’
D类功率放大器产品采用单声道和立体声配置，功率介于2 W和2 x 160 W之间，提供了：
- 过滤和无过滤操作
- 可外部同步
- 表面贴装PSO和PSSO36封装实现了空间优化
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.
