hi,
May I know what is the Op amp offset voltage in the datasheet referring to?
I am using an Analog Device's AD820 Op amp (with single supply) and I found that when I do not provide any signal to the +Input and have the -Input tied to the output, the output is always 5mV. Is this the offset voltage?
How should I do to get rid of this 5mV as it is affecting the operation of my circuit? BTW, I am using this AD820 op amp as a buffer/voltage follower from the output of a DAC.
Thanks for any help in advance.
Regards,
Eric
