  • 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…

  • 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…

  • 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: 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…

  • 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: ic with on chip cold junction compensation and amplification

    Hello Divya,

    ADI thermocouple amplifiers such as AD8494 and AD8495 are designed for J and K-type thermocouples, which were chosen for their sensitivity, availability, and relatively wide linear temperature range. Some legacy parts such as the AD595 can…
