• Ask a question about LTC2387-16


    As below, this is the description in LTC2387-16 datasheet. It says that VCM is not recommended for single-ended to differential circuits that pass the VCM noise to only one ADC input.

    I don't know why? would you please explain it in details or show…

  • RE: Adding Gain to ADC Drive Stage of LTC2387-16 - Noise and Distortion performance considerations

    I am going to assume you are sampling the LTC2387-16 at 15 MSPS. Using the Precision ADC Driver tool you can simulate the ADA4945-1 + LTC2387-18 with and without gain and evaluate parameters like noise, distortion and settling. 

    A quick simulation in the…

  • LTC2387-16 and REFBUF to REFGND capacitor

    Dear Community Members,

    We want to use LTC2387-16 in out project but for some reasons we can not use 10uF 0805 capacitors (no certified components avaiable). The datasheet recommends to use 10uF X7R 0805 capacitor between REFBUF to REFGND pins to decouple…

  • Clocking LTC2387 and jitter performance.


    I am developing a data acquisition board with LTC2387-16. I read the datasheet and looked at the reference design provided in the ADC's webpage. 

    I know that, to achieve the desired SNR performance you have to have a really clean clock(less…

  • LTC2387 input protection


    I am desining a data acquisition system with LTC2387. I am worried about the ADCs' inputs.

    In the datasheet the absolute max. value for the IN+ and IN- pin are specified as VDD + 0.3V which is 5.3V. In my design the front end can swing up to…

  • LTC2387-18 clock problem

    Hi, I've attached a picture of my setup for the LTC2387-18 SAR ADC. My setup is the exact same as in this video (they show it at 2:22): 

    The only difference is my signal generator but I don't believe that is a problem because my oscilloscope seems to…

  • RE: LTC2387 returns DCO clock but no conversion data

    Hi Marius,

    Can you provide a scope photo showing CNV, DCO and DA along with a schematic?

  • HMC900LP5E compatibilty with LTC2387-18


    As datasheet says HMC900LP5E has 2vppd output and LTC2387 has maximum 4.096V diff-input. i want to use the whole range of LTC2387. Is there any way i Can use this low pass filter in front of this ADC (ltc2387) through which the full scale range of…

  • RE: LTC2387-18 ADC Input Driver - Fully Differential Amp v's Two Unity Gain Buffers

    The Precision ADC Driver tool allows you to quickly determine the trade-offs between various ADC driver options for the LTC2387-18 ADC and many more precision ADCs.

    The tool provides simulated performance for noise and total harmonic distortion for the…

  • LTC2387-18 Test Pattern & communication

    Hi All,

    I am trying to receive test pattern from LTC2387-18 and I am a bit confused with what I see on the oscilloscope. I send 9.7 MHz CNV (green) signal to the ADC from the clock distributor. After I sent CNV, I wait for 74 ns and I start generating ADC…
