• RE: Recommended 1.8V regulator for 8 DDS chips

    Hi rrosario ,

    I am going ahead with ADP3339 for my design.

    I am using one ADP3339 / 4 DDS(AD9959) chips.

    Thank you,

  • ADP3339s in Parallel

    Hi all,

    The data sheet sheet for the ADP3339 states the the values for the divider resistors, R1 and R2 are chosen to produce a temperature stable output.

    Should I not place several ADP3339's in parallel for this reason?

    The data sheet also says…

  • Thermal Information

    For carrying out the analysis the following part specifications are necessary:
    1)Power Dissipation (W)
    2)Junction Temperature (TJ)
    3)Case Temperature (Tc)
    4)Junction to ambient thermal resistance (θJA)
    5)Junction to case thermal resistance…
  • RE: ADP3339AKCZ-5-R7 voltage drop

    Hi Ajith,

    What you are seeing at the output makes sense, with an input voltage of only 5V, you are operating in the dropout region and the highest voltage level you can get at the output would be 5V minus the dropout voltage(voltage drop in the pass…

  • ADP3339 minimum input power and tolerance

    According to the datasheet ADP3339 has a 2.8 V to 6 V input voltage range. We currently use this device in our design which feed in only 2.48V at the input due to design limitation. I understand that this is not ideal but so far we have minimal fall-out…

  • AD8336 Output signal level

    I assembled the circuit that was referring to the Figure5 in the AN-934 in order to make the operation test of the AD8336.

    In order to operate the AD8336 by itself, we have entered a 250mVp-p sine wave.

    When I set GNEG=0.75V and GPOS=1.5V, output signal…

    Hello,

    The user guide can be found at the following link:

    Evaluating the AD8283 and AD8285 Evaluation Boards [Analog Devices Wiki]

    I have attached the schematic files for the board.

    Please let me know if you need anything else.

    Thanks!

  • RE: Crosstalk in Multichannel High-Speed ADCs

    Crosstalk is defined as the measure of any feedthrough coupling on to the quiet channel of a multichannel ADC. It is expressed in decibels as a ratio of the energy of the aggressor (active channel) on that of the victim (quiet channel).

    Crosstalk can…
