Other Parts Discussed in Thread: OPA350
Dear Specialists,
My customer is considering LMV771.
He has question about deviation of some specs.
Could you please advise?
---questions---
Acccording to the Lecture Manual of TI Precision Labs of Op Amps(P.5),
typ value of Offset Voltage and TCVos is within +/- one sigma.
The device is OPA350.
Could you please see attached file.
(1)Is the bias current specification ± sigma like the offset voltage?
In case of LMV771, Vos(typ) is 0.3V, TCVos(typ) is 0.3V,Input offset current(typ) is -0.1pA and Input offset current is 0.004pA,
these specs are ± sigma. Are these correct?
(2)Which is LMV771, CMOS or Bipolar?
A post of E2E listed below says, calucration to total Vos is different from CMOS and Bipolar.
CMOS is root mean square, Bipolar is SUM.
(3)When I also consider bias bias current, could I think same as (2).

I appreciate your great help in advance.
Best regards,
Shinichi
