  • Forum Post: Re: ISO7241A datasheet clarifications

    Thomas Kugelstadt
    Sorry , I had to check out the new graphic capability. It works. By the way, below is an isolator life time comparison. The expression "working voltage" or "Viorm" is the voltage across the isolation barrier ( or from input to output) for the entire, rated life time of the isolator...

  • Forum Post: Digital Isolator for an "Analog" application

    Tony Sproul
    Hello, I'm interested in using one of the TI digital isolation devices ISO7220 or perhaps the ISO7520 in an analog application. In reference to the the Texas Instruments "Interface Guide", page 10, http://focus.ti.com/lit/sg/sszt009d/sszt009d.pdf there is listed a key feature that...

    ISO7221M: I am interested in the indirect ESD or indirect-air rating of the device. I can find Human Body Model ( 4kV in the datasheet ) but do not see a rating for indirect. I am expecting a number like 16k volts. Can you let me know how to dind this information, I do not see it in the datasheet. ...

    Hi Thomas, I do not believe I ever received the schematic, just your list of parts. Can you resend the schematic or just a crude connectivity diagram? tnx,

    Hi Thomas, I think this will work for me with changes to the breakdown voltages (e.g., capacitor breakdown voltage ~ 6KV) to not be destroyed by defibrillator pulse and provide proper isolation. tnx, Charlie

  • Forum Post: ADS1118 followed by ISO7241C reads always 0XFF

    Ankit Kumar
    Dear Sir, I am using ADS1118 and to isolate the SPI port, i have used ISO7241C. When i read data on MISO pin after ISO7241C, i always read 0xFF. Is it due to the wrong isolator used because ISO7241C has TTL input thresholds? Please guide me? should i have used ISO7241M? I also suspect that...
