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

A customer had a question on the AD8222. A number of parts had shown offset and gain fluctuations over normal operating temperature, placing them out of specification.  The customer asked whether the "plastic glass transition temperature" of 130°C requires…

我用一个ADR03做为3个AD8222的基准，测试时基准有变动，请问怎么解决？

Hi,

I am using AD8222 in differential output configuration.

My Vs+=5 and Vs-= GND

According to the data sheet my input voltage range should be from 1.9V to 3.9V( -Vs+1.9 to. +Vs-1.1).

So, I given a differential input 1.15 V centered at 2.5 V swinging…

We are using an ad8222 configured as a differential amplifier as in figure 49 of the data sheet.  We have +IN2 tied to AGND and REF2 tied to +Vs, with +Vs is set to 5.0v and -Vs is set to 0v. This should provide a common mode output voltage of 2.5v.  The…

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…

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…

Hi,

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…

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…

尊敬的ADI 应用工程师，

       最近我用了AD8222B 类的双通道仪表放大器，我们搭建了电路，并测试了一下两个通道的共模抑制能力，发现单个芯片的两个AD8222B的通道差异很大（7dB差异）,而两片AD8429B差异却不到0.5dB,并且不同AD8222B的同一个通道的

差异也很多，能否解释一下可能的原因。@
