FAQ
I've done a bit of reading on the operating principle behind the auto-zero amplifier, but have some questions for our particular needs.
Is it appropriate to assume that in a "quiescent" state, where the amplifier non-inverting input is at ground (V…
Hi!
I try to simulate a high-side current measurement circuit. But when i simulate with different temperatures the current output curve moves (due to offset) much more than I expect.
For the AD8538 the offset voltage drift is about 0.03uV/C. So when…
My research has pointed me to a link

Unfortuantly that link is now dead but I have found the webarchive version: Using a Thermopile Sensor in IR Digital Thermometers…

Hi Harry,
I've tried with AD8535 and AD8552 but the problem is not fixed.
The output is still effected by temperature. And I found new problem.
With the same circuit (just change opamp), there are the different frequency output
- With AD8542:…
Bruce,
You didn't say what the corner is, etc. Did you use the Filter Wizard to design the HPF?
What do you mean by LP resonse?
Can you attach schematic and also freq response plot?
The op amp in the AD8231 doesn't have a part number; it…
