• Output code format of LTC2500-32's 32-bit no latency composite code mode

    Hello

    Now I want to use LTC2500-32 and LTC6363 to sample AC signal.And I use 32-bit no latency composite code mode which a 24-bit code representing the differential input voltage.I want to know which is the sign bit in the output data.In my code, the MCU…

  • Front-end analog BW of LTC2500-32

    We are planning to use this LTC2500-32 in receiver section, where the information is centered around 5MHZ with information BW of 50 kHZ (a suitable BPF will be provided) . Can we use LTC2500-32 with nyquist zones upto 5MHZ of RF signal.

  • Exposed pad(Pin 25) of LTC2500-32

    Hello,

    I would like to ask if there is any problem with leaving the exposed pad(Pin 25) of LTC2500-32 floating.

    Thanks!

  • LTC2500-32 step response figure29 in the datasheet

    My customer asked me some question on Figure29 in the LTC2500-32 datasheet.

    1.  what is output sample number(horizontal axis)?

    2. what does D1(n) mean? DF=1?

    3. what is theDF setting for LTC2500-32 OUTPUT SAMPLES DOUT(k) ?

    4. would you expalin what SI…

  • LTC2500-32 can't work with 7.5V Vref voltage appear

    When I was using ltc2500-32, the ADC was able to work normally. After a while, the circuit board was connected with + -20v to supply power to the amplifier, and then the busy signal of ADC disappeared and no longer worked. The VREF voltage measured by…

  • 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…

  • LTC2500-32

    Hi

    I am testing averaging filter in LTC2500-32.

    The test conditions are as follows.
    - Preset Mode(PRE PIN '1', SDI '1') : Averaging filter, with DGC and DGE off
    - MCLK : 2000sps
    - DF : 20

    I read the ADC value through SPI every 20 MCLKs using…

  • ltc2500-32 ,preset mode,averaging filter

    By setting PRE high, I am choosing to use one of the two preset filter modes as shown in Table 4 of the data sheet. With SDI high I am using the averaging filter.  So what's the DF of this filter type?Does it mean that the preset mode has no frequency reduction…
