您好!
我想找一款能够功率放大40khz波形的功率放大器,
音频功率放大器都是对0-20khz的声音放大的, 找了好久都没找到可以对40k频率波形进行功率放大的集成芯片。
如果没有这样的集成芯片, 能给我推荐下用分立原件搭功率放大器的电路不? 比如D类功放中的H桥电路怎么搭
谢谢 !!

你好!
可参考:
OPA541 - 80V supply with 10A continuous output
OPA544 - 70V supply with 2A continuous output
OPA548 - 60V supply with 3A continuous output
OPA549 - 60V supply with 9A continuous output
选型参考:
1. H桥的本质结构就是4个MOSFET,en.wikipedia.org/.../H-bridge
