Instrumentation Amplifier model to fulfill that requirements

Hello,

I am coming from mechatronics background so never been acquainted with how noise is computed at certain frequency. I am also looking for the best Analog Devices instrumentation amplifier with the following requirements:

  • High CMRR (>100 dB)
  • Single supply 
  • Low Noise (as low as possible)
  • Rail-Rail in/out
  • Price won't be an issue

All help is appreciated thanks. If an example of computing noise in/out, I would appreciate it. Thanks

  • Hi Wbadry,

    Please check this article which could guide you on designing high performance systems with low noise instrumentation amplifier: https://www.analog.com/media/en/technical-documentation/technical-articles/TA10718-0-4_12.pdf

    In choosing parts for your circuit, it would be helpful if you could give us some details of your applications so that we could recommend the suitable parts that is designed for that specific applications.

    If you are looking for very low noise instrumentation amplifier, please check the AD8429, AD8421 and AD8422(rail to rail output only). Also please be aware with the diamond plot limits of the inamp and it was well explained on this video: https://www.youtube.com/watch?v=5qVVAt_XImE

    For inamp with rail to rail in and output, please check LT2053, AD8233 (rail to rail out only)

    We have a very broad portfolio and if you could give us more details about the industries you are into then we could advise more accurate parts for your applications.

    Best regards,

    Emman
