• AD5721R

    AD5721R fits our application concerning its specifications, 0-10V, +/-10V output etc. but we require the input data rate is higher because the 10 MHz sine wave signal is converted by ADC and after software processing it is convered to analog signal that…

  • oscillating output AD5721R

    Hi everybody,

    i've a problem with an AD5721R controlled by an FPGA. When I update the output from input register (i'm trying to have a continuous voltage) the output starts to oscillate.

    In the attached file there's a print from scope where i…

  • AD5721R Circuit Implementation Questions

    I'm hoping that I can just keep posting questions in here as I get them and people with experience with this chip or similar and circuit design can chime in and help.

    So here's the goal.  I will be pairing this chip with a Teensy LC in a vehicle…

  • AD5721R Output Range vs Supply Voltage

    I can't find an "output swing" vs supply voltage spec for the AD5721R, only a list of its selectable output ranges and its max/min supply voltages.

    My question is how much if any "overhead" do I need to provide in the analog supplies in…

  • AD5721R芯片SDO管脚输出不正常






  • For the AD5721R what mode should I select if I use VDD=+5.5V and VSS=-5.5V to generate a  +/-4.5V Vout? Shall I use m=8 and c=4 ( +/-10V range) or m=4 and c=2 ( +/-5V range) ?

    The transfer function is:

    #AD5721R range setup

    Vout can not reach +/- 10V if VDD=+5.5V and VSS=-5.5V. Vout can only reach +/-4.5V due to the 1V drop. But how shall I program RA to get +/-4.5V Vout?

    The documentation states that the register RA is…

  • How to calculate settling time for DAC?

    Dear Sir:

                    I want to used AD5721R/AD5761R to produce arbitrary waveform (frequency=100kHz , amplitude=0~10V) to drive a device. But , How to calculate this condition (frequency=100kHz , amplitude=0~10V) through settling time? Does AD5721R/AD5761R…

  • RE: Output voltage range without external operational amplifier on AD7305 and operational sequenceI


    A 12-bit part, AD5721R, is the closest part I can recommend. Is your controller capable of sending 24-bit SPI frame? For which application are you going to use the part?



  • AD5761/21/R FAQ

    Q1. What external devices does the part require to operate as spec’d in the datasheet?

    A1. The AD5761R/AD5721R are 16-/12-bit Voltage output DAC which integrate a 2.5V 2ppm/˚C typical internal reference as well as reference and output buffers. The…
