Dear sir,
Excuse me. I measured the input offset voltage of TLV2401 on TI EVM board by the topology below. (VCC=5V)
The measured offset voltage of one sample is about 400uV, but the other one is about 1200uV.
I know the input offset voltage spec. in the datasheet is 390uV(TYP) and 1200uV(MAX).
But in the datasheet page8, figure2, the input offset voltage is almost zero when common-mode input voltage=0V.
Why??? Would you please explain the difference?
Thank you very very much.
