• Use AD5683R to adjust the voltage reference of AD9744

    Hi,

    I want to build a precision arbitrary waveform generator using AD9744 and AD5683R, where AD5683R is used to adjust the reference voltage of AD9744.

    1. I found that AD5683R is buffered DAC with internal precision 2.5V Vref, can the output of AD5683R…

  • AD5683R VOUT problem

    Anybody help me.

    I setted AD5683R from 0 to 65535 at command Write DAC and input register.

    The output voltage is from 1.25V to 2.5V.

    I don't know how to voltage output to 0 volt.

    Normal DAC minimum output was 0 Volt I know.

    I couldn't set output…

  • RE: AD5683R External Reference

    Hi,

    thank you for your help.

    The AD5683 has a min order quantity of 3000 reel so i need the AD5683R which i get in 1000 reel....

    So i need to stick with the AD5683R.

    Is there a way i can be sure that my reference (ADR4540ARZ) with 4.096V and the internal…

  • RE: AD5683R SPI destruction

    Hi,

    The issue described is pretty strange... if the incorrect SPI mode, the device just will ignore the message.. or sample the signal in the wrong point of time, but it will never damage the inputs.

    From your issue description, seems to me that the…

  • Power-up sequence of AD5683R

    Hi,

    There are description about power-up sequence of AD5683R in the datasheet, P.26.

    What happen If I couldn't keep the power-up sequence?

    (The device will be broke or just the specification will change?)

    Is there another rule about power supply…

  • AD5683R SDO Pin location

    Hi,

    I am trying to interface with the AD5683R using SPI.

    SCLK, SYNC and SDI are visible on the board, but I am unsure as to which pin hole represents SDO.

    I am inexperienced in interfacing between modules so any help would be greatly appreciated.

  • RE: AD5620 or AD5640- Using Vfb to control the DAC output

    Hi Freddy,

    You need to close the opamp loop so, the answer is no.

    Say that, you can use the AD5683R....

  • AD5683R internal Reference long term stability

    Hello!

    I not found on datasheet information about AD5683R internal reference long term stability.

    Interested about voltage deviations by day, month, year.

    I need it to decide using internal reference or external like REF192.

    REF192 datasheet have…
