• AD5620 Model Options

    i have a question about AD5620 Model Options.

    what difference between AD5620A..., AD5620B... and AD5620C...? Difference is only in relative accuracy between models (A the best?)

    next, AD5620-2-3 parts include an internal, 2.5 V, 5 ppm/°C reference,…

  • AD5620 Serial Interface Problem

    Hi

    I'm using a AD5620 nana-DAC part. I have an intermittent failure. Sometimes the part does not respond to serial interface commands. The voltages remains at 0V even though I'm sending serial commands to it. If I cycle the power to the device, the problem…

  • AD5620 as amplitude control AD9834

    Hi,

    I have to do Sinus generator based on AD9834 with amplitude control AD5620.

    I have become Sinus on output of AD9834, but it looks like AD5620 doesn't work.

    I can not set output voltage of AD5620 wiht ATmega16, does not respond to SPI interfacing…

  • EVAL-AD5662/AD5660/AD5640/AD5620

    Hi everyone!

    I'm using EVAL-AD5662/AD5660/AD5640/AD5620 and have AD5660 as my DAC and I noticed that there are grounding problems to the AGND and DGND pins of the evaluation board. It is said in the datasheet of the evaluation board that the analog GND…

  • Low Ref on AD5620. Why?

    Hello

    I measure voltage level on Vref pin. He is +2,483V. I changed supply voltage from + 5V to + 6V. Vref is const.

    In the datasheet specified tolerances Vref from +2,495V to +2,505V.

    Why value on an output is other than declared in datasheet?

  • zero code error and offset error of AD5620

    I am using AD5620, the expected Vout should be 0.8V according to the equation: Vout = 2 x Vrefout x (D/2^N), where D=1310, but I measured the Vout is around 0.84-0.85V. And I measured the zero code error is around 0.3V.

     I checked the datasheet where…

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

     

    Hello,

    Using the AD5620 or AD5640 with Vref=1.25v.

    1- According to the datasheet Vref pin must be shorted with Vout and it gives a maximum output voltage of 2xVref with resolution of 2xVref/2^N.

    Question: Is there a possibility of connecting Vfb…

  • the adjustable amplitude of square wave generated by AD9834 and AD5620

    hi,

    As we all know,the adjustable amplitude and frequency of sinusoidal wave can be controlled by combining AD9834 with AD5620. I want to know whether the amplitude of square wave generated by AD9834 and AD5620 also is adjustable. If not, can other method…

  • 关于AD9834和AD5620输出的方波幅值可调的问题


    AD9834与AD5620级联可产生幅值可调、频率相位可调的正弦波。请问下,对于AD9834产生的方波结合AD5620,其幅值仍旧可调么?若不可调,怎样能实现或者说怎样改进让其产生的方波幅值可调?谢谢。

  • 关于AD9834和AD5620输出方波幅值可调与否的问题

    你好,请问下能否通过AD9834与AD5620配合直接修改程序获得不同幅值(连续可调)的方波信号?
