• ADA4500-2 - Driving an ADC

    Will the ADA4500 drive an Analog-to-Digital Converter?


    There are many considerations when driving an ADC.  A primary consideration is
    the noise and linearity of the amplifier driving the ADC. The effective
    resolution of an ADC is affected…
  • ADA4500-2 - Resistors around the amplifier

    What resistor values should I use around the amplifier?


    ADA4500 has a low voltage noise density of 14.5 nV/√Hz.  Placing a 1KΩ resistor
    with thermal noise of 4 nV/√Hz at the input of the amplifier increases total
    input referred noise…
  • ADA4500-2 - Charge-pump noise affect

    Does charge-pump noise affect the signal quality of the ADA4500 output?


    The ADA4500’s charge pump operates at a very fast clock speed, varying between
    3.5 MHz and 5MHz over its supply voltage range. This high frequency does not
  • ADA4500-2 - Output driven beyond one of the supply rails

    What happens if the output is driven beyond one of the supply-rail Voltages?


    The ADA4500 has been designed to accommodate output overload.
    Op amps typically are not designed to tolerate overload; they can take tens of
    microseconds to…
  • ADA4500 understanding load capacitance effects


    I'm using the ada4500 in a product design and have a questions regarding how load capacitance effects the part.  Could someone explain what exactly figure 37 in the data sheet means?  What is small signal overshoot and how do I apply that graph…

  • Amplifier gain offset configuration help


    I have somewhat of a general op-amp configuration question and need to get some feedback from someone more experienced in analog design than me.  I have the below schematics:

    This is a single stage in an analog input channel for a product.  The…

  • 2*2 MIMO setup


    Iam interested in implementing a MIMO 2*2 scenario where i will use 2 fpgas (1 as the transmitter and 1 as the receiver) where each one  will be connected with one AD-FMCOMMS3-EBZ.
    So the setup will be :
    FPGA_1 + AD-FMCOMMS3-EBZ_1 =Base stati…

  • ADV7623 support 4K/30p 4:2:2 ?


    I want to know ADV7623 Support Video Format.

    ADV7623 support 4K/30p 4:2:2?

    ADV7623 TDMS Frequency:225MHz.

    So,I think ADV7623 support 4K/30p 4:2:2.

    Did anyone use 4K/30p 4:2:2 at ADV7623 Eva Board? 

    Best Regards.

  • ADV7610 registers 4:2:2


    Thanks in advance.

    I have a input video signal whose format is: YCbCr (Digital YUV) 20 bit (10 chroma + 10 luma).. 1080p60 (1920x1080 60 fps).

    As I can read in this forum ADV7610 only supports four modes for SDR 4:2:2:
