• RE: procedure with ad5761

    Hi Renato,

    You may want to take a look at this wiki entry that discusses the AD5761R - No -OS Driver. The AD5761R is the basically the same die but with an internal reference. Note that we only provide the code as is and we do not provide any software…

  • 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…

  • Proper power supply sequence for AD5761R

    Hello all,

    On our prototype, we are using an AD5761R powered by +3.3V (DVcc), +12V (Vdd), -12V (Vss). The component was damaged (exhibiting overcurrent on DVcc and Vss lines) during the prototype tests and we wonder whether there should be a specific…

    Hello, 

    I would like to make clear about EVAL schematic of AD5761R/AD5721R.

    According to UG-751

  • RE: Regarding AD5761 DAC

    Hello,

    I also use this ad5761R,and i can readback the register correctly,but the Vref=0.75,not  the 2.5V, i think the schematic is not correct,can you share your schematic ?

    thanky you very much!

  • AD5761R内部参考电压示波器万用表测试均为0.728V

    您好,在使用AD5761R这块芯片时,设置控制寄存器为内部参考电压,并且Vref这个管脚也通过了10nF电容接地,但是我在使用示波器或者万用表测试时,该芯片这个管脚一直输出的是0.738V,不是2.5V,导致Vout无论怎么设置输出都是-0.6V左右。请问我应该怎样检查出现这个问题的原因。令:对于控制寄存器中CV[1:0]和PV[1:0]这几位的设置还是不太清楚,zero scale,midscale,full scale 都是针对什么参考而言的呢?请大家帮帮忙分析分析吧,谢谢!

  • DAC芯片AD5761R读数时没有数据的咨询

    您好,我正在使用AD5761R这款芯片,在进行写数据时,用示波器能观察到写入SDI的数据电平,但是在对SDO进行读数据时,一直为0。不知道是不是对这块芯片进行初始化不正确。datasheet中我只看到了对control register的配置,并且也不太明白CV[1:0]和PV[1:0]这两个zero scale,midscale,full scale的设置分别是什么意思。我对这两个都选择了midscale的配置。首先我对control register进行写了0x0402AD这个数据,为了读取这个数据是否写对了…

  • 关于AD5761R的使用问题。

    我最近在使用AD5761RZ这款芯片。能够正常读、写控制寄存器,输入寄存器、DAC寄存器。读返回值也正常。能够产生所需要的电压。但是在连续产生不同电压(产生一个信号波形)时不能正常工作。比如在一个在一个死循环里面,产生不同的电压值,间隔用延时,实现个信号波形。发现输出不正常。还没找到问题在什么地方。我用STM32107VC连接AD5761R.
