• LTC2508-32 SDOA has no output

    Hello,

           I have a problem using LTC2508-32.The chip's  22-bit no latency output has data output, but the 32-bit filter result has no output. In my design,RDLA is pulled down to GND, MCLK=1MHz, DF=256, each conversion period has a busy signal, but the…

  • RE: Design LTC2508-32 so as to perform precise voltage measurements

    Hi Shane,

    Rather than trying to shift the ADC supply voltages which may not be entirely successful, why not use a fully differential amplifier such as the ADA4945 to shift the input voltage of your signal into the range compatible with the ADC.

    (2) Never…

  • RE: Which parts/strategy do you recommend for isolation of ADI's 32 bits SAR ADC?

    On behalf of Eric Benedict:

    Which ADC are you interested in and what are your application requirements? 

     

    The LTM2893 could be a good solution for the LTC2508-32 which is configured with pin strapping. 

     

    The LTC2500-32 has features which require SPI…

  • RE: LTC2512-24 开发

    您好,请问你的问题最后得到解决了么?我在使用LTC2508-32芯片过程中遇到了和你一样的问题,22位无延时端口B有输出,但是32位滤波端口无输出。MCLK=1MHz,按手册将DF设置为256,用示波器观察DRL信号每隔65ms被拉高一次,SDOA一直无输出,希望得到你的回复,谢谢。

  • LTC2508 - Large Ripple during large signal settling transient

    Hi

    According to the pictures in the datasheet, the LTC2508 has up to 500uV pp of noise during large signal settling. Is this really correct?

    If yes, where is this noise coming from? Does it disappear after the transient? What's the frequency range?…

  • 32位ADC芯片的前端设置问题

    在寻求一款32位ADC芯片,需要的采样频率在4kHz~16kHz,ADC输出频率1kHZ,有效分辨率至少20位。

    希望ADC前端的低通滤波把系统带宽限制在840Hz。查询到LTC2508-32,LTC2500-32以及AD7177-2三款产品,

    想了解如下情况:

           1、不知道还有没有可推荐的32位ADC?

           2、我的信号是单端输入,应该需要一个单端转差分的运放,希望该放大器有可配置低通滤波器,这样可以简单地设置

    低通滤波截止频率在840Hz,能否推荐一些满足要求的放大器?

  • LTC2500-32

    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?

                 Thanks!

  • 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…

  • LTC2500-32 REF pins

    Hi,

    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…
