I am planning to use the ADA4841 to drive the AD7980 and am having trouble finding the input current range of this amp. Is it 10nA to 10uA?
Are you referring to the input currents such as Ibias and Ioffset of the ADA4841? If yes you can see it on the specification under DC performance. Usually in amplifiers, the input voltage range is the specification that you need to satisfy for the amplifier to perform well. I am curious of what you mean by input current range. Can you tell me more about this specification and why you need this on your circuit?
