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…
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…
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…
