• Request the spice model of ADA4830

    Dear Analog,

    Could you please provide the spice model for ADA4830-1? I want to simulate CN-0273 using different first stage op-amp, and I also want to test some ADC driver scheme using dual ADA4830 or ADA4830-2.

  • Differential video transmission with ADA4433-1 and ADA4830-1


    Thanks for providing the spice model of both ADA4433-1 and the ADA4830(-1).

    I'm trying to design a DC coupled differential transmission system using the ADA4433-1 and the ADA4830.

    The overall gain from input (ADA4433-1) to output (ADA4830…

  • (ADA4432)To make Pseudo Differential output

    Hi !

    Our customer want to input Pseudo Differential CVBS to ADV7281A-M but they don't have the video source.

    So they are thinking to make Pseudo Differential signal from single CVBS video source.

    I was reading ADA4432's datasheet.

    I understood…

  • ADA4830-1 in pseudo-differential mode... input trace geometry?

    Hi,..I'm using difference amp ADA4830-1 in conjunction with decoder ADV7180 (Circuit Note CN-0263), to receive a CBVS video signal.  My question has to do with the ADA4830 input trace geometry on my circuit board.  Given that I'll be connecting the…

  • Understanding the compatibility between Amplifier and Encoder


    Our requirement is that an Y/C NTSC video signal be converted to a PAL video.

    We selected two amplifiers, a decoder and an encoder. We would like to know if the parts selected have proper compatibility and also serve our purpose.

    On the input…

  • RE: 50MHZ BW Instrumentation amplifier

    gain is 2X , usually there is a resistor in in-amp that you can adjust.  

    ADA4830 is good, but I need at least +-7.5 voltage span. My output is 0-5, input is -2.5 to 2.5v. 

  • RE: Setting of ADA4433-1


    Please refer to Figure 55 on page 22 of the ADA4433-1 datasheet. This figure illustrates how to connect the ADA4431-1 to a differential input and how to convert the differential output of the ADA4431 into single ended using the ADA4830.
