ADC-216 resolution question

Post by vicb » Tue Aug 26, 2008 4:00 am

I have successfully written an application in LabWindows 7.11. I have a query about the what the best resolution is, though.

For example, if I select the +-10mV range with adc200_set_range, is it possible to get 16 bit resolution on this range, ie can the resolution be 10mV/32767?

It seems to me that unless I'm doing something wrong, the best resolution I can expect is about 1 mV. Thanks for any help.

Hello vicb,

The resolution is 16-bit on all ranges.

If you are experiencing resolution below that, you may wish to look at the application environment for sources that dominate the noise floor.

Regards
John
