• Looking for op amp that can be powered by single source  24 VDC

    I am using a AD8496 chip and need to boost this signal from millivotage to voltage signal. Teh only power supply I have to run both devices, AD8496 and op amp, is +24 VDC and COM. So Need an op amp that will fit this application. Temp range is -10-25…

  • RE: AD8495 cryogenic temperatures error

    I also trying to compare the results of the transfer function with the Type K Vtc values, but is not mat

    With the voltage from Table 3 from AN-1087 (Thermocouple Linearization When UAD8495/AD8496/AD8497).

    But the results do not match.

    Also would I…

  • RE: AD8221ARM THERMOCOUPLE

    Hi abedgarr,

    I think we'll be needing more information on your side in order to give a more effective suggestions or feedback.
    May we ask what's your input level? I'm interested to know why you need a gain of 5000 on your application.
    Have you…

  • 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…

  • Problem with AD8293G160

    Hi,

    I have a problem with AD8293G160. (please see PDF attachment).

    The Gain in my test is not 160. What is wrong?

    This is my first thermocouple circuit and i selected AD8293G160 for it's very low cost.

    I absolutely need a very cheap circuit for…

  • AD8495能对E型和J型热电偶进行检测么?

    大家好!

           本人正在使用AD8495对热电偶温度进行检测。

           由于项目要求能够检测电路能够在K、J、E的热电偶中通用,并且考虑到目前一级代理E络盟不再继续采购AD8496(针对J型)使得AD8496价格升高,AD8494(针对J型)的2℃精度对应的测温范围不能满足项目的要求,所以想利用AD8495对K、J、E的热电偶进行检测。

           想问一下:

           (1)对于K型热电偶,AD8495的输入输出关系是Vthermocouple = (Vout - Vref - 12.5mv)/122.4。

            那么…
