• AD5737的问题

    各位高手好,我想咨询一下关于AD5737芯片的多通道的使用,是不是四个通道的电流输出端口可以直接分别外接电阻到同一个地,也就是芯片的那个地?

  • AD5737 : To reduce full scale current value

    Hi,

    I have few questions on understanding working of AD5737

    1. What is the relation between RSET resistor & RL (load resistor) ?

    2. How do I set a RSET value to control my DAC output range as 0-1mA.

    3.What all settings should I have to consider apart…

  • SPI communication with 3 AD5737

    Hi,

    I am working on 3 AD5737 using single SPI communication from MCU.  My requirement is that 12 Channels to provide a current output of 4 to 20mA where i should be able to control each channel independently.

  • AD5737使用问题。

          ADI的技术工程师们你们好!

          现在项目中打算采用这个芯片实现多路电流信号输出,自己做的板子电路和参考原理图上的类似,所有控制引脚都已经引出来,现在有下面的问题。

         1、现在使用的是官方AD5755中模拟SPI例程,读取设备的寄存器一直是0xFFFFFF,初始化流程如下:

          LDAC、CLEAR、RESET拉高->等待20ms->LDAC、CLEAR、RESET-拉低->等待20ms->RESET-拉高->SYNC、SCLK、SDIN拉高->等待20ms…

  • AD5737上电后芯片过热

    您好,用到贵公司的AD5737芯片,芯片上电后会发热的比较厉害,用SPI读取寄存器,SDO总线也没有接到任何数据,SPI的SDI总线的数据均符合AD5737上面的时序,目前不知道问题出在哪里,附上原理图,希望您能够看看是否有错误的地方,万急!!!

    其中 电感没有10uh的  目前用1uh的在调试,其他的均和原理图一样。问题找了好久都没有结果,希望能够尽快恢复!!谢谢!!不胜感激!!

  • AD5737是否有替代产品

    在新设计中使用了AD5737,但是昨天发现官网上已经不推荐使用了。

    请问ADI是否有其他替代芯片或者替代方案呢?

  • Enabling all 4 channels of AD5737 simultaneously

    Hello,

    I  am currently working on AD5737 with output current range 0mA - 20mA.
