Enhanced MFD beased on DDS

[Freelander]

Hi to all,

I'am working on the Carl's MFD project, and I need to improve this device with a DDS (Digital Direct Synthesis),

see diagram:


Thanks to share your experience on this subject.


Many thanks

What's your opinion on this basic shematic?

Let's make lock on this DDS kind found on Ebay:

At my MFD i use the TDA 2030 for more power.
The DDS that you show is OK.

Thanks ***Geo*** for sharing info, here your answer on the schematic.


Thanks to check here the Vs and V input, from your experience, to get those 2 values simultaneity do you use serial batteries?




I'm waiting feedback friends

Here the TDA2030 datasheet of parameters and standard schematic.

Be careful the V+ of DDS !!!!!
I think that at your schematic the Vin is the power supply.
