Hi, I am currently using this product " Stanford SR570 — Low noise current preamplifier" for my application. I need your assistance in recommending me the amplifier IC which can meet the same current specification. Looking for your response. Thanks
We don't have any five dollar op amps that replace a $2,600 test instrument.
If you have a limited range of current, max voltage noise, max current noise,
specs that will meet your requirements, we might have something.
Thanks, But then what are these are specifically for Low Input Bias Current Amplifiers (<100 pA) | Analog Devices . Thanks
There are 10-20 specs on the average op amp. An op amp may have low bias current, but
a limited frequency range, high voltage noise, limited temperature range, etc. You can compare
the SR570 d.s. sheet with an op amp and see what the difference is.
The main purpose is the amplification of current lying maximum in the range of nA/V. Looking for your response. Thanks
Look at the ADA4530.
What is the minimum low power amplifier IC is provided by "Analog" on shelf and what is the value for minimum supply current that is being supported by that IC.
AD8500 is 1 uA supply current.
