• RE: AD8494 - remote cold junction sensing

    Hi Jan,

    Thanks for reaching out to us.
    Although for the AD8497 since its cold junction compensation feature uses an internal temp sensor, the thermocouple's cold junction and the AD8497 should be kept at the same temperature for best performance.

  • EVAL-AD8494 power supply

    Hi

    I am FAE in Japanese distributor.

    Our customer will evaluate EVAL-AD8494.

    UG1421 mentions EVAL-AD8494 needs both +5V and -5V.

    AD8494 works at single 5V supply.

    Can EVAL-AD8494 work at single 5V supply?

    Best regards

    N.Kokubo

  • RE: AD8497 connected method

    Hi Patrick,

    You may refer to the application information in page 14 of the AD8497 datasheet where an example of a basic configuration for the AD849x with a J type or K type thermocouple input was discussed. See link AD8494/AD8495/AD8496/AD8497 (Rev. C)…

  • RE: Looking for Thermocouple Amplifier with signal filter

    Hello Sir, 

    Thanks for the response. I have gone through the interface selection table and I think that AD8494 J-type thermocouple amplifier would be useful for my work. I wanted to check if this amplifier can handle the high sampling frequency rate like…

  • AD594 wiring

    Can I wire a single J-type ungrounded TC to a pair of AD594 units - in parallel?  I would like to connect to unit 1 normally, but to the 2nd unit wired in reverse.  My purpose is to have a reverse polarity detector, where unit 2 would drive an LED whenever…

  • RE: 我想问一下有没有针对s型热电偶丝的冷端补偿芯片

    据我所知ADI目前只有适合J、K、(T)三种分度号热电偶的放大器,如:AD8494/5/6/7,AD594/5/6/7。AD595的冷端补偿虽然是按K分度号热电偶校准的,但有可以用于T分度号热电偶。

  • RE: AD8494ARMZ and AD8494CRMZ

    Hi isilvki,

    A and C are grades of the AD8494. The C grade is generally tested with tighter specifications compared to the A grade. In the case of the AD8494, if you look at the specification table on page 3, the C grade has better overall temperature…

  • RE: AD623 Thermocouple Amp

    Hi Brett,

    What's happening is that the output is saturated. You need to drive the REF pin to some voltage inside the operating range of the output. By the way, in case you missed it, we do have a family of In Amps for thermocouple applications (which…
