• LTC2500-32 REF pins


    There is 2 REF pins for the reference signal of the LTC2500-32 and I wonder if I can use one pin directly connected to the decoupling capacitor and the other to sense the reference voltage with the Vout_S of the LTC6655 (low drift precision reference…

    When PER and SDIA pin are high level DRL has normal pulse output.

    DRL signal cannot be output in other modes.

    SDOA output is always low when reading data.

    Is it caused by the wrong timing in the diagram?


  • LTC2500-32 ENOB

    Hi ADI Expert, 

    According to the datasheet page8 of LTC2500-32 Performance characteristics,

    SNR: 116dB, SINAD:114dB @ 128K FFT, SSINC filter. thus I calculated the ENOB= SINAD 114dB -1.76dB/6.02 = 18.6 Bits.

    The datasheet page32 table2 is noise performance…

  • LTC2500-32

    Hi there,

          I would like to use LT2500 in my project. The input signal is about 0.1Hz~10Hz, +/-10V, single end. The low noice and low drift come first. And I notice that LTC6363+LTC2500 in the typical application of datasheet. I just donot know how to…

  • RE: I want to use STM32 spi to read 24 bit data by using a LTC2500-32.

    Hi Shadow,

    Look at page 50 Figure 53 of the LTC2500-32 data sheet. The schematic and timing diagram shows how to share SCK and SDO.

  • LTC2500-32 - DF by 2


    My question is concerning the digital filter on the LTC2500-32, I would like to down sample by 2 (DF=2) with the averaging filter, but there is no word to program the DF filter accordingly if it can be done.

    So in the data sheet in the table "ADC timing…

  • LTC2500-32 :what's default value of Control Word??

    i use LTC2500-32 and i want to use Control Word to set DF and filter type, and my set value of Control Word is 0x845,(DONT USE DGC,DCE,DF=4,filter type=SSINC)  BUT  after i  write this reggister, the 2500 don‘t  work anymore. actually,before i set reggister…

  • RE: LTC2500-32 using ADC 7 Click

    with a single 5V supply, the input voltage range goes to only 4V with high linearity and the output voltage range only swings to within a few millivolts of ground or +5V.

  • LTC2500-32 Digital Filters Coefficients

    On page 26 of the LTC2500-32 Datasheet is told that:
    "The FIR filter coefficients for each filter are available at www.linear.com/docs/55712."
    On page www.analog.com/.../ltc2500-32.html I don't see him.
    Where I can find this document…

  • RE: LTC2500-32, SYNC pin left floating. Implications?

    The SYNC pin should not be left floating. If SYNC floats high, the LTC2500-32 will not function properly. Tie SYNC low and see if the board works properly.
