I am using an AD8222 for a weight scale application. Is it possible to use the 2nd op amp in the AD8222 in a non inverting amplifier configuration? or is this not advised? If it is not advised, then is their a single op amp version of the AD8222? Also…
Ms. Anna,
I have attached my ckt for AD8222 using MAX406 as a voltage follower. The only problem I see is that I don't know why there is a high resistance on AD8222 [+ pin].
I have AD8222 amplifier eval board. I want to place Buffer(voltage follower) op-amp in front on AD8222. Application is pH measurement
Hi,
I'm under testing AD8222.
Is there anybody point out what should I do to fix abnormal output?
My expectation on OUT1/2 is 2.2V
Test Condition :
Vs+ = 5V, Vs- = 0V
REF=2.2V
Input : Floating
Test Result :
OUT1 = 4.1V
OUT1 = 0.6V
My customer will use AD8222 with the same conditions as the attached ADIsimPLL simulation file, including in/out signal.
There was no error in ADIsimPLL simulation. However, In-Amp Diamond Plot Tool was failed as below.
Is there a problem using…

I am wanting the ability to switch in a gain at power-up and am considering using a ADG1414 serially-controlled octal SPST switch to be the switch since I am I/O limited. The gain of the instrumentation amp will either be one or a specific other value…
Hi niranjan,
Yes. You have it right. Whether you drive the inputs differentially or fix/ground one input, the input voltage range does not change. The voltage at each input must be kept within the specified range, regardless of the voltage at the other…
Hi
I really find the instrumentation amplifier, AD8222, AD8224, AD8426 with differential output really useful. But I have a question regardign the noise spec when using these in differential output mode. With the term noise spec I am referring to terms…
