• RE: Resistor feedback DAC AD7538KR.

    Hi. Without signal chip select in microcontroller don't grabed pins (use 4 DACes ) and scheme is asserted manager i don't use  AD5556. For future design i have in mind AD5556.

  • Rofs pin of AD5556

    Can the Rofs pin of the AD5556 be left unconnected when used in unipolar two-quadrant mode?  It appears that this would increase the feedback resistance from 5kΩ to 10kΩ.  Would this then also increase the output range from 0V - Vref to 0V to 2Vref?

  • RE: AD7840: no RC network shown in datasheet for LDAC pin permanently low.Please show the right fig in Fig 19

    Hi,

    You may want to check out the AD5546/AD5556. It can be used in parallel mode similar to the AD7840.

    Regards,

  • Is AD5556 usable without negative voltage?

    I proposed AD5556 DAC to be used for two different functions:

    1. Programmable Voltage Generation between 0V and Vref
    2. Programmable Current, always positive current.

    The designed board will only have positive voltage sources.

  • RE: AD5553 Operating Temperature

    Hi John,

    Would you have any other specifications that you would need to take note of? Could you share what is your target application? Knowing these, we can pick DACs that will better suit the application that you have. I have made a list of DACs bel…

  • RE: low noise DC amplifier design

    Hi  jk4556,

    If your voltage output should be around +-10V I would recommend use one opamps to increase your voltage reference to +10V.

    this will keep your noise levels quite low selecting the appropriate resistance.

    In a second stage you can use a multiplying…

  • RE: How do I determine the appropriate amount of compensation capacitance using the ADA4522-2 and the AD5556?

    Hi,

    The data sheet says a 20pF capacitor is generally adequate for the compensation. The compensation capacitor prevents ringing and instability at the output of the DAC. If you want to compute for the capacitance, you can use the equation below. Note…

  • AD5553 Operating Temperature

    I see that the operating temperature of the AD5553 is -40 to 85C.  Is that air temperature around a mounted device on a standard board or is that case temperature?

    Thanks,

    -John

    Hi John,

    The operating temperature ranges seen on the data sheets are…
