    Hi Tan, ADC noise is not included and need to be added using above formula - INL, DNL, Eg and Eo are all DC parameters and do not include the ADC noise. Having said that, as discussed in https://training.ti.com/ti-precision-labs-adcs-statistics-behind…

    Hi Jan, In addition to Clemens suggestion, you may also try INA823 as shown in the image below. Jan Croes said: has a bandwidth over of 4kHz If this is the hard requirements at gain of 1000 V/V, then you may have to pick higher BW instrumentation amplifier…

    Allen, The difference of 20nV/rt-Hz vs 21V/rt-Hz is insignificant taking into account that the normal noise process variation may be as high as 20%. As far as the output swing goes, the only difference between INA823 and INA826 is 150mV to negative rail…
