The output impedance of AD8231 is very low, though I can't say what is the exact value, the recommendation of <50 ohm source impedance will be satisfied by the AD8231.
In addition to that, you need to consider if the amplifier can…
can use AD8231 extra op amp for comparator application. Thanks~
Yes I used the op-amp in an AD8231 to implement the high-pass filter.
Unfortunately we don't have a spice model available for AD8231. Also, we don't have a SPICE model that is close enough to the AD8231's performance. However, if you would like to simulate a three-opamp instrumentation amplifier behavior, you…

I used AD8231 in our circuit as below picture (For +VS=5.06V supply, with nCS, A0, A1, A2,-VS to GND) , We have some issue when we test AD8231 as below:
1. We tried to short +INA and -INA , the outputA have 2.9mV offset , then I check parameter…
I am looking to use the AD8231 In Amp in my board design but I will not need to use the on board op amp. What will happen if I leave the op amp inputs and output floating?
Thanks for the info.
I have one doubt in continuation to your explanation. If I select 10kSPS data rate, then the ADC will have 100uSec settling time and 100uSec conversion time. Is my understanding correct?
Also in our circuit, we…
Thank you Scott,
I intend use +-5V (total diff 10V) for loadcell. So the maximum common-mode voltage is about +-18mV. The voltage regulator is 7805 and 7905. What is the voltage at the Rg if input voltage is very low (mV) ? I haven't found any information…
