Hello,
I'm looking for a A/D converter with 12 or 16 Bit and up to 10 V input range. DIP/DIL prevered.

Hello,I'm looking for a A/D converter with 12 or 16 Bit and up to 10 V input range. DIP/DIL prevered.
Tried a product search on Digikey, Mouser, Farnell etc?
Why the jump from 12 to 16 bit? What about a 13, 14 or 15bit ADC? 12 to 16 is a huge jump in resolution.
Do you want a serial interface, or parallel etc? Your question is far too broad.
Also look at oversampling and decimation using the AVRs internal ADC if you don't need high conversation bandwidth.

12 or 16 bit resolution needs very careful circuit design. You can't get that resolution by sticking a DIP package in a breadboard.
The range isn't a problem. You can divide voltages down to the right level with 2 resistors.
16 bit is tricky - for instance you need to understand precision circuit design, sources
of error voltage in opamp circuits, error budgets, etc.
You'll need a precision voltage reference, low-noise power supply, good groundplane
PCB, etc etc. Reading "The Art of Electronics" chapter on precision circuits would
be a starting point.
However if you are only dealing with audio (no DC accuracy needed) then things are
simpler, except you'll have problems coping with the datarates involved, I2S bus isn't
for beginners...
