I am testing and developing a little circuit that needs a 16bits VDAC, but I could only find a 8 bits VDAC component.
Can someone say some hint?
Entering "vdac resolution" (without the quotes) into the keyword field at top of this page will give you something to read.
There is no VDAC with more than 8 bit resolution, but there are some techniques and examples on how to increase that.
I imagined what you had said but I would like to confirm that no component was being left behind in the PSoC Creator Catalog. I made a search, but I could not find any conclusive post about It. Thanks very much about this info!
this is Cypress Application Note covering the tricks to improve resolution of existing DAC
if you look on INL and DNL curves, there is only subliminal improvement over 8-bits. Your best bet is ADC Feedback DAC, which is the slowest one, but offers 12-bit. Maybe you will be able to get a little further.
To get 16 bit I used to play with MAXREFDES24 4x16-bit dac industrial board from Maxim Integrated, which I can provide you with some (rather unpolished) code:
For the moment I will consider using the VDAC8 component because it is simpler and I may have to worry with other parts to project know. Thank you!
