Hi Sadashiva,
This approach is the same as what I proposed in the previous reply. The red boxed section is an instrumentation amplifier (IA), which is the same as INA317. In fact, INA317 will outperform the discrete IA configuration with LMP2011 or other…
Hi Patrick,
The INA317 and/or INA333 below may be used for AD8237 replacement.

Hi Mauro,
Thanks for your post, I can help you.
Looks like you're searching for a low voltage instrumentation amplifier for a cost sensitive application. I definitely want you to check out INA317 ( www.ti.com/.../ina317.pdf) and help me answer the…
Hi Jan,
I think that Instrumentation Amplifier (IA) will meet your requirements, such as INA333 or INA317 or INA188 part. Enclosed are the links that it may help you to select your IAs.
BTW, you can use bipolar for INA333 or INA317 family, except the…
Hi Sandheep,
Do you have any recommendations on low-noise regulators for this application? My PCB has both 5V and 24V available.
If your 5Vdc and 24Vdc power sources are directly connected from wall wart adapter, you need to place some filters after the…

Hi, my customer is looking for the least noisy and drifty OPAMs . Typical gain at low frequency…
Hi Art,
The 5.5 mV is coming off of a quarter bridge setup (strain gauge) which is getting its power from a 10V rail off a USB DAQ.
Per your requirements, I put together two stage strain gauge amplifier circuit with Gain = 1818 V/V.
The strain gauge is…
Hi Davide,
I do not recommend INA828, since you have a single supply rail at 3.7Vdc. Your input Vcm does not have the range per your application.
Based on your early design requirements and compression transducer's datasheet, I did the following simulation…
Hi Alexandre,
I did some searching per your application requirements. Here is what I came up with, no particular order.
1. OPA188
2. OPA221
3. OPA333
4. INA317 (-40C to +125C)
Please let me know if these will meet your need.

Raymond
Part Number: INA333 Other Parts Discussed in Thread: TINA-TI , , INA317 Tool/software: TINA-TI or Spice Models Hi，
I am Daniel. I want to use INA317 and INA333 to measure the unblance of resistance bridge. I know the two instrumentation amplifiers need…
