• 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…

  • Using AD5542 in bipolar mode

    I need an output swing of -5V to +5V, so I'm using the congifuration included in the datasheet. I'm using a Vref of 5V and a AD8643 as the output buffer. I decided on the AD8643 because it's a part that's present in the rest of my circuit, but I can change…

  • AD5542 in bipolar mode - opamp recommendation

    Hi!

    I'd like to use the AD5542 DAC in bipolar mode.  The DAC's output would be in the -2mV....+2mV range. In the datasheet there is a circuit which presents a possible approach to the bipolar mode and it emphasizes the importance of picking the right…

  • 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

  • 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.

  • 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…

  • AD8643 for DAC bipolar output

    Using the DAC AD5542, I need an output swing of -5V to +5V. I'm using the configuration included in the DAC datasheet. I'm also using a Vref of 5V and a AD8643 as the output buffer. I decided on the AD8643 because it's a part that's present in the rest…

  • 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…
