Khaja,
The data sheet for this part is very good at explaning how it works, and it also gives application information for help on how to use it.
Please refer the the product page for this part for the data sheet, along with other helpful, technical…
Hi Joaquin,
As Carlos and Jason mentioned above, there isn't really a way to make the INA138 work well in this application because regardless of how you scale RS, the bias currents are going to dominate your measurement.
If the solutions Jason presented…
Hi Sami,
Add the bypass cap to the reference as Timothy suggested. To reduce noise from the reference, I would also recommend a series resistor (~50K) between the input and the reference, and a large capacitor (~10uF) from the input to ground to add…
Thanks for the file Wendy, not really a slew limit issue, more of a BW issue on both the low and high side, attached - half wave amplifier tune up.docx
And here is the SSBW shape of that last ckt, much better flat region mid band,
Other Parts Discussed in Thread: LMP7711 Hi All,
I am looking for a single supply(preferably 3V) op amp for microphone preamplifier.
Any suggestion would be helpful.
Thanks & Regards,

Paul,
I just found the common mode capacitance vs. common mode voltage graph for the 6211. For my application, it looks like it'll be about 7pf. Is the front-end's topology similar to that of the LMP7711 so that I can I safely use 2-3pf for the differential…
I had sent this link to someone else recently, and was reminded that planet analog broke the links to expand the figures so they are unreadable - here is the original pdf,

Morning Sonja,
Yes, those specified input C appear to be inthe TINA model, testing thus far shows this to be a very good model,
