• RE: AD5449 : xCLR pin

    Hello,

    Thank you for your reply.

    I am using the AD5449 with the circuit like Figure 38 in the datasheet

    I have tried the Fast Transient Test(IEC61000-4-4) to the substrate.

    In the test, the noise was impressed to the AC100V line of the substrate.

  • Single-Supply Voltage-Switching Mode of AD5449

    Hi all

     

    I have a question about AD5449.
    When we used AD5449 as Single-Supply Voltage-Switching Mode,
    VREFx output voltage was 3.88V max with VDD=5V、VIN(IOUT1x、RFBx)=5V.
    Is it impossible taht VREFA outputs 5V ?

    The datasheet says "In this type of application…

  • AD5446: SFDR

    1. In the AD5446 datasheet, It just has a SFDR specification under fout=50KHz
    and 20KHz. And it does not specify it under fout=500KHz. I also checked AD5449
    datasheet, it offers this spec under 500KHz fout. Could you give me AD5446 SFDR

  • AD5449 mixed mode DACloading query

    Can i mix and match the DAC loading protocol interface mode.

     

    No, do not  mix and match with different modes of operation. We advise to
    either use one or the other i.e.(SERIAL INTERFACE SPI mode) as defined in the
    datasheet rev.D . i…
  • AD5449: Output noise spectral density

    My customer considers to replace AD7568 with AD5449. In their application the
    noise performance between 1Hz and 100Hz is very critical.

    The “Output Noise Spectral Density” they can cope with should be
    <20nV/sqrt(Hz)  @ 10Hz –100Hz…
