What is the real offset voltage of the opamp for PSOC4
I do some tests with PSOC4 opamp, the result is not really good:
I configure a opamp as a follower and put a signal like sinus from 0 to 100mV and i get the output signal ohne if the input signal > 49mV. I tried all configurations and the results are the same.
I checked the PSoC4 PSoC 4200 Family Datasheet_001-87197_0B.pdf and this is in the spec:
SID288 VOS_TR Offset voltage, trimmed 1 ±0.5 1 mV High mode
SID288A VOS_TR Offset voltage, trimmed – ±1 – mV Medium mode
SID288B VOS_TR Offset voltage, trimmed – ±2 – mV Low mode
So, I'd like to know what is the real offset of this chip, has someone experence with this issues?
Thanks a lot for any infos!
