• 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…

  • RE: AD5412 or AD5735 1-5V voltage output

    Hi Ricky,

    Code conversion is one method of achieving this.

    Another method is that the AD5735 comes with gain and offset registers that could allow the user to offset the output by 1V during calibration.

    See the following sections in the AD5735 datasheet…

  • RE: Output Protection Circuit for AD5755 ?

    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.

    A ferrite…

  • 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, …

  • 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…

  • 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…

    What is the difference between the AD5755, AD5757, and AD5755-1?

  • 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…
