LMV321-N-Q1: OPA output capability and compared with OPA2365

Part Number: LMV321-N-Q1
Other Parts Discussed in Thread: OPA2365, LMV321, TLV6001-Q1


I'm used LMV321-N-Q1 for PFC input voltage feedback.  

OPA supply voltage is 3.3V.

When opa input is 110v, the output voltage be clamped arond 2.06v.

(CH1: OPA input  CH2 : OPA output  CH3:OPA supply voltage)

But if OPA supply voltage increase to 3.5v, the output voltage match the OPA setted gain.

I also tried to change OPA  to OPA2365, the opa output is correct and don't need to change supply voltage to 3.5v or other.

Does the OPA's output capability is affected by supply voltage?

My english is not good, sorry.
