Hi Sammi,
Anything beyond about 132dB is unmeasurable. Why would you care at a gain of only 100?
To put it in perspective, 120dB is 1uV/V, 132dB is 0.25uV/V, swinging the max 5V of an OPA388 amounts to about 1uV worst case. Going a few more dB is…
Hi Matthew,
The reason I asked you to plot the data was to see if there is an oscillation as I suspected. You should be able to get your system to work using 3.3V, but you need to eliminate all the potential problem areas. The first is with respect…
Saeed,
In general it is recommended that you do not use op amps as comparators . The only exception to this is in cases where you are using an op amp package with multiple amplifier (e.g. a quad op amp, 4 per package), and you only use a subset of the…
Hendrik;
You could use the precision OPA227P on +/-12V or +/-15V supplies. It is in a DIP package.
Most new op amps are being introduced in surface-mount packages only; there is so little demand for DIP packages that it is not worthwhile for IC…
Hello Iwata-san,
Please see rule of thumb #2 in the attached article for an explanation about how noise increases with temperature.

Linfeng,
You can use the REF5025, but you will have to reference the part to AVSS (-2.5) instead of GND. The output of the regulator will actually be 0V. We have done something similar with the ADS1248EVM. I've attached the schematic for you to review…
Hi Richard Zuniga,
The ADS1258-EP has an associated VID from the DLA, see the link below for a PDF of this information. Is this sufficient for your application?
