Hi,

When intput voltage overs Vref, does output data keep 0xFFFF?

Hello,

The ADS8320 outputs data in sraight binary and has an input voltage range from 0 to Vref.

Correct, if the input voltge is Vref, the output will be at full scale and output code will be 0xFFF

The below excerpt from the datasheet break it down further

Cynthia-san,

Thank you for your reply.
Is "0xFFF" correct?
0b 1111 1111 1111 1111 should be 0xFFFF.

You are correct, 0xFFFF

The datasheet mistakenly shows it, and I repeated that mistake.

I will make a note of this mistake to get it corrected.

Regards

Cynthia
