1. Does AD9288 (8-bit A/D) accept 0.5V or 1.0V reference voltage ?That is,
REFinA or RefinB = 0.5V or 1.0V ?
2. Can I simply feed in my single-ended analog signal to AinA (or AinB)and
ground the corresponding complementary input (i.e. AinA_bar or AinB_bar) ? Do
I lose accuracy or performance by not buffering the differential inputs by Op
For your first question, AD9288 reference voltage is from 1.2 to 1.3. It cannot
support 0.5 to 1.0V.
Yes, you can just feed the singel-ended signal to the Ain and Bin. But
the performance is not good as the differential inputs. For best dynamic
performance, impedance at Ain and Ain_bar should match.
