• LTC2983 ADDITIONAL CONNECTIONS

    Hi,

    I was working on a project and it required me to record temperature values. Initially, I used 4 RTD's with the step up as follows and it was working fine. The excitation current used was 50uA

    Now, I need to use 6 RTD's but I can only fit 5 RTD…

  • LTC2983

    I am using a LTC Demo Kit (2209A), Experimenter Board (2210A) and Linduino to evaluate the use of a LTC2983 as a Thermocouple datalogger.

    The Thermocouple inputs are differential using the specified input circuit from the datasheet (see below) i.e Ch1…

  • LTC2983 20ch Type-T Thermocouple maximum scan rate

    Hello,

    I would like to use LTC2983 or 2984 for Type T thermocouple measurements.
    10 sensors (full usage of 20ch and no capacitor filtering at inputs).
    Also only 2 conversion method, no need for open wire detection. 

    What is the fastest rate I could scan…

  • RE: LTC2984/LTC2983 Measure RTD/Thermistor with 3 Connections

    Hi Mirco, 

        The configuration will work (is legal) - but you will have to determine if it will be useful in your application. Consider the resistance of the wire connecting the RTD sensor element. If you are using a PT-100 which is only 100 ohm nominal…

  • LTC2983 Demo Board

    Hello,

    I'm using a LTC2983 demo board with LTC2983 Testbench program.

    Demo Board: 2026C + 2209A + 2210A

    Hardware connection: CH1-- 2k sense resistor -- CH2, RTD PT-100 sensor => CH2, CH3, CH4 connected, COM connected to GND pin

    When I run the…

  • LTC2983 differential measurements

    "The thermocouple negative terminal is tied to CH TC-1 for differential measurements. This node can either be grounded or tied to a bias voltage."

  • Quikeval LTC2983 -999 measurements

    I cant get the quikeval program with LTC2983 to stop giving me -999 measurements. It worked in January with the Demo Circuit 2210A for measurement of a PT-1000 resistor with a 2000k Ohm Rsense. Now we have manual wiring to the reistors instead of the…

  • Temp measurement using LTC2983

    I am trying to make a temperature meter with a Thermocouple T-type sensor using the LTC2983.
    Please let me know if there is a circuit to reference.

  • LTC2983 Interrupt/SDO

    I have a test circuit with the LTC2983CLX (attachment). The circuit is build as  in the datasheet (Caps are placed as in the datasheet).

    Grounds and VDD pins all are connected and supplied.

    What I have measured: VDD=5,2V, LDO pin is at 2,5V. Reset input…
