• AD5749 VFAULT

    Hello.

    Dose it have a VFAULT function ?

    Pin Function Descriptions in datasheet  is on SDO/VFAULT at 1pin.

    But it is not descibed VFAULT.

    Best regard.

  • AD5749 Vref and Vin

    Hi all! I was evaluating the AD5749 as current loop driver in substitution to a more space consuming OpAmp solution.

    I would like to convert a 0 to 3.3V signal to a 4 to 20mA but I see from the datasheet that the Vref and the Vin should be 0 to 4.096V…

  • RE: 我想做4~20ma电流输出有没有什么好的芯片

    AD420和AD5420是4-20mA输出串行输入DAC，cn0270应用笔记有完整的参考电路。

    http://www.analog.com/media/cn/reference-design-documentation/reference-designs/CN0270_cn.pdf

    AD5748、AD5749、AD5750、AD5750-1、AD5751等都可以讲电压输入转换成4-20mA电流输出，cn0203应用笔记有AD5750-1的完整电路。

  • Analog Current Output with in the pA or fA range

    Q 

    For our optical oxygen sensors we use currently the ADuC7023 in combination
    with AD5695 for analog output with 0-2.5V. An industrial customer requests now
    an analog current output in the range 0-100nA (yes, nanoampere!). Could you
    advise…

  • RE: 能否推荐一款隔离4-20mA

    隔离单芯片没有发现，实现你的需求：

      -- ADI 方案：隔离 -- ADuMxxxx SPI 接口隔离芯片。

                                        速度很低时可以用廉价的光藕隔离--处理后不高于50KHz SPI，无处理 10KHz SPI

                             DAC -- ADI 有很多满足要求的，可以自行选择

                        4-20mA -- 推荐 ADI 的 AD5749，内部集成电流驱动高压MOS，环路电压可以高达 55V

    有厂家的芯片内集成有DAC，但功率元件需要外接，也没有隔离
