• AD5735 DCDC Converters problem

    Hi

    Recently, i got some problems(fault) with  AD5735 AD converter chips. ( only channel A output problem )

    i think it's because the SW(DC to DC converter switching) output was not normal. but don't know it's due to an external circuit or chips…

  • AD5412 or AD5735 1-5V voltage output

    Hello All,

    One of my customers is considering utilizing AD5412 or AD5735 DAC with current and voltage driver for their new designs.

    His product need 1V to 5V output in addition to 4-20mA and 0-10V output.

    AD5412 and AD5735 have 0V to 5V output driver…

  • Can the AD5735 be used in single supply configuration?

    I received this inquiry from a customer:

    In our design the AD5735 will only be used in a unipolar output mode, therefore I would like to know if the AD5735 AVss pin can be tied to gnd instead of a negative supply. I would prefer not to have to add a…

  • 关于AD5735为什么会烧毁？

    ADI工程师您好：

         我是北京天时前程自动化工程技术有限公司的研发工程师，现在应用ad5735时遇到了如下困难：

    故障原因

    电路按官网提供的AD5755参考电路做的，我们用的是AD5735，现在生产20套做老化测试，老化到第三天时，板子没有问题，第四天上午时，关了一次电源，20分钟后上电，板子没有出现问题，下午，又断了一次电，20分钟后上电，有6块板子不工作了，检查发现AD5735的VCC与GND之间短路，但是拆掉电路中10uH的四个电感，VCC与GND之间不短路了，把电感剥开后，发现电感线圈绝缘漆已坏…

  • Using the AD5755 family in Applications Without Dynamic Power Control

    For applications that do not require Dynamic Power Control it is possible to set up the AD5755 family of products without the use of the DC-to-DC converter. This reduces the number of external components required and is useful for low power applications…

  • RE: 求助：有没有什么芯片可以代替AD694？

    没有完全替代的AD694的芯片，

    但是可以考虑AD5755-1  AD5735-1  他们都是4通道 4-20mA 变送器

  • RE: 请问ADI有把模拟电压信号直接转换成4-20mA电流信号的产品吗？

    最重要的要看达到的精度， 输入信号的类型

    从输入信号的类型分：

    1. 模拟输入， 4-20mA 输出， 其中 又可分为 两线制 的4-20mA 芯片，  三线制的芯片

    其中两线制为 AD693，

    三线制为 AD694  AD5747/48/49/50/51

    2. 数字输入， 4-20ｍＡ输出， 精度最好， 其中 又可分为 两线制 的4-20mA 芯片，  三线制的芯片

    其中两线制为 AD421 AD5421，

    三线制为 AD5420/10  AD5412/22  AD5735/37  AD5755…

  • Lack of SPI slave select

    Hi,

    I was considering using several AD5410 instead of a complex AD5735 in my circuit but I've found out that AD5410 does not come with a SPI slave select. Is there another way to individually control each converter in a single SPI bus?

    Thanks, …

    Hi VAV,

    The AD5755 datasheet is soon to be updated, the recommendations in the AD5735 datasheet are already up to date and provide more explanation on this external protection. I have also included a copy of these recommendations attached.
