• Capacitor for LTC2986 VREFOUT

    • I have a design based on the LTC2986, but currently having trouble about capacitors of VREFOUT.

      The design files, including Gerbers and PDF artwork, as well as PDF schematic can be found on the DC2608A, but I am confused about the capacitor of VREFOUT…

  • LTC2986 grounded thermocouples

    Greetings

    We have an application where we need to measure temperatures with unshielded, welded K-type thermocouples. The thermocouples are spot-welded onto a conductive surface, so the thremocoules are grounded. In a different application the thermocouples…

  • Schematic for LTC2986

    Where can I get good resolution copies of the LTC2986 artwork, at least the top layer silkscreen and/or schematic?

    It would be great if someone can provide it.

    Regards

  • Question about LTC2986

    Hello,

    I received a question about LTC2986 from our customer. He is checking LTC2986 by following setting.

    When the customer sets YOKOGAWA 2553A to 0.0 deg C. The measurement result of LTC2986 is -0.5 deg C.

    Then he sets 2553A to 100.0 deg C. The measurement…

  • LTC2986 channel configuration

    I'm looking through the LTC2986 datasheet and I'm a little bit confused about the external configuration for the single ended and differential thermistors.

    If I understand correctly, the device has ten channels, but can only be connected to three…

  • LTC2986 Direct ADC Measurements

    Hi,

    I have a couple of questons about the direct ADC mode of LTC2986. Please take care of this case.

    - What is the maximum sampling  speed of internal 24 bit ADCs in the direct ADC mode?

    - How can I know conversion start and finish in the direct ADC mode…

  • Rsense accuracy for LTC2986 and other questions

    Hi,

    I'm looking to use a LTC2986 to measure Pt100 RTDs and wanted to know the accuracy requirement for the Rsense to meet the temperature error specifications. I couldn't find the error contribution anywhere in the datasheet but I guess since it's…

  • LTC2986 measure differential thermocouple with universal input circuitry

    Hi,
    I'm planning to use a LTC2986 to measure a bunch of different sensor types with only one hardware setup. In the datasheet I found a schematic of a typical application (last page) which seems to work just fine for my application. I was just wondering…

  • LTC298X ADC Internal Clocking and LTC2984/LTC2986 Universal Typical Application Example

    Hi 


    I just want to confirm the following: 

    1.The internal ADC's on the LTC298X parts are clocked by an internal oscillator and not through a derivative of the SPI clock? 
    I figure it would be illogical for a register based part like this to draw its conversion…

  • Are LTC2984/2986 software-compatible with LTC2983?

    We have a design based on the LTC2983, but currently having trouble procuring them for an upcoming build. I see that the LTC2984 and LTC2986 are very similar parts, with the addition of EEPROM for storing data through power cycles. Assuming we don't need…
