Hello there,

I am looking for precise analog signal isolator. I have gone through ISO1X series.

Please suggest me a precise analog signal isolator for medical application. 

Thanks and Regards 


  • Hi Suraj, 

    Are you able to provide a system block diagram to show how this analog signal isolator will be used? 

    If you go to ti.com/iso you can find TI's whole portfolio of isolators including digital isolators, isolated gate drivers, isolated amplifiers, and isolated ADCs. My assumption is that you are looking for an isolated amplifier, but please correct me if that is not the case. 

    See if any of these isolators look like they meet your needs. If not, please feel free to reply to this thread and someone should get back to you on Monday during normal business hours (Dallas TX timezone). 

    Thanks and have a great weekend!

    Hi Dan,

    I am using H-bridge based circuit which gets analog input form MCU as shown in block diagram.

    I want to isolate analog signal output from MCU that goes to amplifier. So kindly suggest approaches related to same.

    Hi Suraj,

    Take a look at the ISO224 or the AMC1311 to see if those may work for your needs.
