  • AD594: Type T thermocouple

    Q 

    I was just wondering if the AD594 Monolithic amplifier would work with a Type T
    thermocouple?

     

    A 

    You can use the AD595 with type T but not the AD594, see the following extract
    from the datasheet for explanation:

    Because of the similarity…

  • AD594: ESD and EMI protection

    Q 

    Our question is if the thermocouple inputs on the amplifier are EMC protected
    or if external components are required. If so, please advice a solution that
    has no effect on the performance of the amplifier.

     

    A 

    The inputs of the AD594 have standard…

  • AD594  AD595 for N type thermocouple

    Q

    AD594/595 is monolithic thermocouple amplifiers
    with cold junction compensation for J type thermocouple. Could it be used with
    N type thermocouple?

    A

    AD594 and AD595 are Pretrimmed for Type J (AD594) or Type K (AD595)
    Thermocouples. But they can…

  • AD594: Voltage changews with supply voltage

    Q 

    We are currenty evaluating the AD594 Monolithic Thermocouple Amplifier with
    Cold Junction Compensation. We notice that the output voltage from the device
    varies when we increase the supply voltage. The output also changes when we
    touch…

  • 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…

  • AD594 Output thermocouple type J

    I would like to use  the basic connection/single supply operation of the AD594 with a thermocouple type J, so I connected it like shown in figure 1 of the datasheet.

    Instead of a clear signal of 250 mV I got signal noise around 320 mV at temperature 25…

  • AD595: Why are there two different operating temperatures listed in datasheet for the same part number?

    Q 

    In the absolute max rating section of the AD595 datasheet, you quote the
    operating
    temp range as being -55 to +125. However, in the second sentence of the fifth
    paragraph of the Product Description on Page 1 of the datasheet you state 'Both …

  • AD59x Correct Thermocouple Grounding

    Q 

    I do not understand how to correctly ground my thermocouple?

     

    A 

    When using the AD59x, the thermocouple should be grounded at one place, and
    only one
    place. The grounding can occur at the negative input of the AD59x, the positive
    input of
    the AD59x…
