I am using AD8222 in differential output configuration.
My Vs+=5 and Vs-= GND
According to the data sheet my input voltage range should be from 1.9V to 3.9V( -Vs+1.9 to. +Vs-1.1).
So, I given a differential input 1.15 V centered at 2.5 V swinging from 1.35 to 3.65 V to AD8222 with gain 1. I was expecting a clipped wave form at negative half. But I got a perfect sine wave output with gain 1.
Attached is the simulation of the test circuit I am using. THS 4520 is the fully differential amplifier I am using to make my input wave form differential. What could be the reason for that?
