• AD5542 grounding

    Hello,

    Table 6 of the datasheet of the AD5542 ( Pin Function Descriptions) points out the differences between the digital gnd pin and the analog gnd pin. This makes me think to separate the two pins by connecting each of them to the DGND plane and the…

  • AD5542 SPI/LDAC to output latency

    Hi ADI experts,

      I need to produce a width-adjustable pulse signal with a resolutioin of 10ns. Thus I use a FPGA which runs at 100MHz to control AD5542:

    1. At time = 0, sending the first SPI/LDAC command to set DAC output to pulse high level
    2. At time = T,…

  • About AD5542's reference

    Hi there,

    I have a question about AD5542's reference.

    The datasheet say reference should be 2.5V like the following?

    Is it okay to apply 5V, right?

     

    From data sheet

    "Voltage Reference Input (Sense) for the DAC. Connect to an external 2.5 V reference…

  • AD5660: Can multiple AD5660 devices be updated simultaneously?

    Can multiple AD5660 devices be updated simultaneously?

     

    No, this is not possible with AD5660, You should use AD5542 or AD5570 as these
    devices have /LDAC pin to achieve this.

  • DAC的输出阻抗及其影响


       为什么不同的DAC的输出阻抗会差别这么大?例如,AD5542的输出阻抗约为62.5Kohm,而AD5360的输出阻抗约为0.2ohm?

    不同的输出阻抗,在后面进行运放缓冲时,应如何处理?

  • RE: Very low noise DAC

    Thanks for the reply.

    The AD5791 is 1.1uV i.e. much worse than AD5512
    The AD5541/AD5542 seem to also be a possible choice

    Thanks

  • AD7546: Glitch perfomance

    We have been using your AD7546KN D-A convertor on our circuit
    boards. As this has been obsolete for some considerable time,
    and as a change in cicumstances has dictated that we now need
    to support this product again, we have decided to redesign …

  • AD5541/2 AD5541A/2A noise specification

    I'm looking for a very low noise 16 bit DAC and the AD5541A and AD5542A stand out with a 0.1 - 10Hz noise specification of only 0.134uV p-p. After a  few moments of reflection though, this seems hardly credible given the noise spectral density is specified…
