- This is the second version of the Class D audio power amplifier project utilizing the IRS2092 protected Class D audio amplifier driver chip and 2 IRFB4020PbF digital audio MOSFETs.
The IRS2092 features an integrated analog input stage that is coupled to the Class D audio amplifier driver stage internally. Two Digital Audio MOSFETs, the IRFB4020PbF, which are specifically made for Class D audio amplifiers, are externally connected to the low and high outputs of the IRS2092. Up to 300 watts can be delivered into an 8-ohm load by these Digital Audio MOSFETS in a small TO-220AB package.
The prototype of this project achieved a measured power output of more than 160 watts into an 8Ω load with ±50VDC power supply rails.
A feature of the 2nd version of the Class D amp project is the inclusion of an over-voltage and under-voltage protection circuit. To improve the audio performance of this version a combination of series-pass and linear fixed voltage regulators were added to provide VAA and VSS power supplies, as well as the power supply requirement of the BiFET op-amp.
The IRS2092SPBF SOIC16N package version can also be used in this project by mounting it into a SOIC16N to PDIP16 adapter. The adapter is then populated into the U2 location on the PCB.
How does Project 56 perform in real world listening? Playing from several CD albums of different music genre, the audio quality reproduced was pleasant and impressive. It's safe to say that the audio quality it reproduced was the most accurate and dynamic as a Class D audio power amplifier could deliver.
I think it is fine that a developer earns some money on a project he has used a lot of time to develop. But it is also fair to open up and be clear about your intentions.
Will you sell documentation, will you sell PCB s, will you sell kits, will you sell finished and tested boards??
Thank you for your thoughts. That's a very good idea. But on the other hand, I don't sell any kits from the projects that I have developed with the only intention of sharing them, as mentioned in my website and in this channel. Everything is DIY from scratch i.e., making the PCB, assembling the PCA to the finished amp. Have fun building your own amp. Information about a project is at my website, www.buildaudioamps.com.
Nice work man!!! Clean and beautiful project!!! Really interested by this project - but!!! Good video and well explained, schematics - but NO VALOR of the components - so I think that you want to sell something - in that case, sorry, not interested at all!!! Cheers!!!
BOM is always available free by request
Nevermind man, if you did not post it, expect that no one ask for info - if it's free, let it free - if is your idea, if is not (you did not provide some link of your inspiration) - leave it! So, cheers BOM! Without any request!!!
