• Correct layout of ADA4937-2


    The ADA4937-2 datasheet states that the ground and power planes should be cleared near the summing nodes and gives an example for the ADA4938-1:

    This is a bit confusing to me because it only looks like the polygon pour on the top layer is removed…

  • Inquiry about the design of the AD9258 and the ADA4937-1


    My customer will use ADA4937-1 and AD9258 at repeater application.

    1. Input voltage range of the Vocm pin in the ADA4937-1 is min 1.2V to max 3.8V. However, the VCM output of the AD9258 is 0.9V.

        The voltage ranges between the Vocm pin and the…

  • Differential Input Configurations For AD9650

    Dear Sir or Madam

    As I found in the datasheet page31 of AD9650 , it mentioned "For baseband applications, AD8138, ADA4937-2, and ADA4938-2 differential drivers provide excellent performance and a flexible interface to the ADC."

    Does it mean…

  • RE: How to get proper footpring for ADA4937-2

    Hi Eric,

    ADA4937-2 comes with a package option of CP-24-10 which is compliant to JEDEC Standars MO-220-WGGD-8. We apologize that there is no bxl file available in the product page. We will have it updated.


  • ADA4937 Load


    I'm simulating the ADA4937 Differential Ampliifier that I will use as ADC driver for the AD9255, with and without output filter.

    It seems that adding the output filter at tha ADA4937 leads to a huge distortion of the output signal.

  • RE: Driver AD9253 using ADA4937

    Dear Flaviano,

    Thank you for using the ADA4937 and AD9253.

    I believe that the output common mode range of the ADA4937 is not quite matched to the AD9253. As you have stated, the VCM output of the AD9253 is at 0.9V. This is outside the range of the ADA4937…

  • ADC driver for AD9255

    I'm planning to use the AD9255 single 14 bit ADC with DC coupled input signals in the dc - 20 MHz range.

    Because of the DC coupled requirement I am looking at ADC driver amplifiers instead of a transformer.

    The AD9255 web page recommends the ADA4937…
