Second Class D Amplifier Using Analog ADAU1592
Loading...
Uploaded by SkankyPistol on Jan 29, 2009
After version one failed, this amplifier was quickly designed and built around an Analog Devices ADAU1592 18W stereo Class D amplifier IC. The purpose of this design was to analyse the performance of the Class D amplifier class in an actual application (albeit not a particularly powerful amp)

I think it will be a while before I can finish my amp build. It uses a DSP board from a Denon AV receiver for Dolby Digital / DTS decoding, so I will add another 4-channel Sure amp for 7.1 surround.
Sounds great already in 2-channel stereo, but I have a fair bit of work to do on the I/V stages and making it look presentable.
I'll post a video when it's mostly working though. (I'm OzOnE_2k3 on diyaudio btw.)

You could try checking out the datasheet for the chip he's using, there might be some schematic in it.

Amazing! i am really getting into the art of making amplifiers and wanted to know if you could email me a schematic of this great amplifier. Thanks

Neat build.
(I'm currently building an amp using the TK2050 Sure modules.)
Ironically I also have one of those aweful Alba DVD players for testing. I think they are cost around £7! lol

Yeah I went for the cheapest half decent DAC I could find for a CD player and found it in an Alba DVD player :o) It also helped when I demoed it for my dissertation - no one would pinch it!
Hope you are going to video your build too, always good to see what others come up with !!!
