• LTC2984 TC CJ Diode Overrange

    Hello,

    I am using the Demo board for the LTC2983 to test both RTD and TC (Type K) circuits. 
    I figured out what I was doing wrong to get the RTDs to work so that is fine.

    However, I am trying to get the TypeK TCs to work to no avail. I have made sure I…

  • Ltc2984/86

    I want to calibrate ltc2984/86 temperature measurement ic. Is there any procedure or any algorithm to do. Like two-point calibration or single-point calibration. How can I reduce the offset error of ltc2984/86?

  • LTC2984/LTC2983 Measure RTD/Thermistor with 3 Connections

    Hi,

    i'm currently looking for an opportunity to save an additonal pin in my design. I'm using the LTC2983 Testbench Tool to evaluate different configurations.

    Variant A is used throughout the documentation as one way to interface a PT-100 RTD…

  • LTC2984 do not respond at all.

    Hello everyone, I am trying to communicate with the LTC2984 after start-up.

    After 200ms the INTERRUPT is HIGH but I try to read de Command Status Register sending 0x030000 thru the MOSI line but the MISO is always LOW. The only change on MISO is when…

  • LTC2984 temperature output resolution using demo code...

    I am currently using the DC2420A demo kit (with LTC2984) to measure temperature.  When I graph the data using the graph button, I see 3 decimals of resolution in the data.  However, when I use the automatic code generation and upload this code to the Linduino…

  • LTC2984 and 4-wire thermistor measurement?

    I would like to use mux chips for measuring many (over 100) thermistors.  The mux chips have too much Ron resistance to provide accurate measurements for each thermistor.  Can I use the 4-wire measurement method (like RTD) but still configure as a thermistor…

  • RE: LTC2984 conversion time question

    Hi Thomas, 

         I answered Ken's question off-line. I will summarize here for reference and if you have additional questions, please start a new thread.  

         Each channel configuration describes a measurement setup for a given sensor. The internal mux configuration…

  • Intermittent invalid data from LTC2984

    We are using LTC2984 to measure temperature from 2 Thermocouples, 2 Diode, 1 RTC and a analog input. We are configuring all the channnels from STM32H753 via SPI and reading the channel data using consecutive convertion method every second. 

    Every second…

  • There was a problem driving the LTC2984 using STM32

    I can receive 0x40 from command register after send 0x03 0x00 0x00,but after configuring channels i can't receive 0x40 if i send the control byte 0x80. and my conversion result memory register always get 0. ltc2984 is fine when i use the dc2420-kit.…

  • What is alternative of LTC2984?

    LTC2984 is not available in stock on all platforms. Is there any alternative part no. for it? Is there a need to modify the firmware for the alternative part no?
