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 all!
I would like to build a thermopile (built in thermistor) circuit which can measure mid infrared spectrum in uV range. I found the following circuit:

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…
ADA4051-1 might not be fast enough. Try it first.
If not fast enough, the AD8538.
Also, put a styroform "box" or shield over the board to reduce air currents.

I have planned to use AD8638 opamp in my project. Am in need of the spice model for the simulations.
Could anyone help me in getting the spice model for AD8538.

How much dropout voltage (Vsys - Vout) must I allow for if I the load current greater than the limits in the datasheet electrical table? Looking at a low-voltage op amp like the AD8538 at Vsys = 2.7V, the datasheet lists a Voh with a 10k load, but what…
你好,如果你要放大的信号不是差分信号的话，就选用一般的通用放大器就可以了，比如：AD8613, AD8538都可以用单电源5v供电，也可以满足带宽要求。
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…
对于运放来讲，您可以选择我们zero drift，例如AD8538、AD8551、AD8571。关于参考，您也可以选择温漂较小的产品，例如：AD688/AD588、AD598/ADR4520等。
