Other Parts Discussed in Thread: LM2904B-Q1
Hi team,
I use LM2904-Q1 for small signal amplification.During the test, it was found that LM2904-Q1 did not meet the requirements of virtual short.TI's technical support staff told me that it was due to the existence of Vos that this phenomenon occurred.The LM2904-Q1 has a maximum Vos of 7mv.
But I tested LM2904B-Q1 in the same environment,LM2904B-Q1 met the requirements of virtual short.The LM2904B-Q has a maximum Vos of 3mV.
So when Vos is small to a certain value, it will not cause the amplifier to produce a phenomenon that does not meet the virtual short? So what is the threshold for this Vos?
Best Regards,
Ivy
