• AD5687 output buffer

    Dear all, 

    How can retrieve from AD5687 datasheet DAC output buffer impedance? Thank you.

  • are there any power up sequence restrictions on AD5687?

    The Vlogic is going to be powered up first. Then Vdd after
    several milliseconds. any issues with this?

  • RE: ad5323 using as programmable attenuator

    Hi,

    1) As AD5323 does not have any information on noise performance/spec, would you consider using AD5687? You can find the noise specs under AC characteristics of the datasheet. More info on NSD can be found on this tutorial and this video.

    2) I'm pretty…

  • Layout of AD5687BCPZ

    Hi,

    I am using the AD5687BCPZ DAC to drive an RF circuit. The control is from an FPGA. I have two different grounds, i.e. an RF ground for the RF circuit and a digital ground for the FPGA. In some DACs, the analog and digital grounds are clearly specified…

  • RE: AD5542 in bipolar mode - opamp recommendation

    Take a look at the following CFTL:http://www.analog.com/en/circuits-from-the-lab/CN0181/vc.html

    The AD5687 is used here and can be used as an output amplifier and a reference buffer.

    Its strange that the output is becoming unstable. What supply voltages…

  • FAQ: nanoDAC+ Family AD531x/AD568x/AD569x/AD567x

    Q1. What is new?

    A1. The nanoDAC+(TM) family offers improved analog performance in terms of INL and glitch energy specifications.. Some members of the family, those with a part number ending in 'R', for example AD5686R, include a  low drift 2.5V…
