• RE: How can i design the 4ch signal conveter of pt100 sensor

    Hi, please take a look at the AD693, it will link your pt100 sensor to a 4-20mA output current.You will need one per channel.

    An Application note is…

  • Is there an AD693 RoHS version?

    Is it possible to get a lead free version of AD693?

     

    I had checked with the product line and there are NO plans to create a RoHS
    version of this product.

    当代的现场仪表,也就是众所周知的智能变送器,是基于微处理器的智能现场仪表,用于监控过程控制变量,例如温度、质量流速和压力等。系统设计人员面临着一种直接挑战,也就是既要融合额外的智能、功能和诊断能力,同时又要开发出能够在4 mA至20 mA的环路所提供的有限功率范围内有效运行的系统。严格的安全标准、空间限制、HART通信、诊断和预见性维护将是未来的主流趋势。

    Hi Bharti,

    I cannot seem to be able to split your concern into a new forum so can you help post this AD693 question into a new Q&A under "Data Converters"?

  • 关于AD693的封装。

    请问ADI

    .AD693AD693ADAD693AQ的封装,请问这两种封装有什么区别,AD693AD的抗辐照性能是否更佳?

    谢谢!

  • RE: How does ADM693 shift the watchdog-timeout to?

    Hi

    I explained this to our customer but he didn't satisfy this reply.

    So can we think the similar characteristic ?

  • The outputs of 'ad8495crmz' are different with AN1087

    Hi all

    I have designed a board with AD8495 and AD693 to measure temperature with a K-Type thermocouple,within the range of 0~400 degrees centigrade.When I use ICE bath to test this circuit,the results a totally frustrated me, cause when I change the…

  • RE: 类似AD5750,只需电压输出

    AD5751也是 电压输入, 4-20mA输出的变送器

    你要求的输入时模拟信号,还是数字信号

    如果是模拟信号,还可以看一下AD693 AD694

  • RE: Loop Powered Transmitter

    Hi Sagar,

    Are the two measurements independent? Current loops support a single transmitter and one or more receivers in. Some transmitters include their own power supply, and a loop-powered transmitter implies that you have a power source elsewhere in…

  • 关于RTD温度测量电路的芯片选择

    我们在做一个项目,是铂电阻PT100温度传感器的信号调理电路,目前较多使用的方案是ADI公司有AD623和AD693两款芯片。ADI公司最新的用于这方面的芯片是什么型号有参考方案吗。
