• RE: CN0357 Board with biased gas sensor (NH3-B1)

    Hi RGERALDO386,

    The current circuit has the working electrode biased at 1.2V provided by the voltage reference ADR3412.

    The easiest way to provide a 200mV is to remove ADR3412 and provide an external reference in its place. But do take note that changing…

  • RE: ADUCM360 内部基准的温飘的问题!

    ADUCM360的温漂指数的正负是无法保证的,只能保证绝对值。如果您需要精度更加高的参考源,推荐您使用ADR3412http://www.analog.com/en/special-linear-functions/voltage-references/adr3412/products/product.html

  • RE: ADE7816 Reference Voltage

    Hi Tim-S,

    I haven't heard of anyone doing this before but It shouldn't be an issue to use one ADR3412 as the reference for three ADE7816's. It is important to note the ripple rejection ratio of the ADR3412 because any instability in the supply for the…

    AD9834 - Is there any way to improve the accuracy and temperature stability of the output amplitude?

    The internal voltage reference have an output impedance of 1kOhm, so could it work to connect a precision voltage reference such as ADR3412 to the REFOUT…

  • ADR3412输出电压波动

    使用ADR3412产生1.2V参考电压,3.3V供电,测量输出只有1.194V,达不到0.1%的初始精度,请问有可能是什么原因造成的?

    另外,电路中有一个5V供电的433MHz无线模块,当模块工作时,ADR3412输出电压会发生较大波动,变化范围可以达到0.04V,完全不能使用,请问造成这种情况的原因有哪些?

  • RE: AD9786内部电压基准的问题

    您好,基准电压跳动可能与电路板上供电,地的噪声相关。可以使用外部参考,用External Reference Mode。您可以看看参考芯片ADR3412

  • RE: ADR280 .1 - 10hz voltage noise

    Hi Jonathan,

    Thank you for your interest in ADI products. ADR280 is no longer recommended for new designs. We suggest you use the newer ADR3412, micro-power, high-accuracy 1.2V series-low dropout voltage reference. It's low frequency noise (0.1-10Hz…

  • RE: CN0287 accuracy analysis

    Hello Willie,

    Thanks a lot from your comments.

    Regarding your comments ,


    • For RTD, as per your suggestion we will configure ADC for unipolar input. This will result in better accuracy.
    • In thermocouple voltage reference (ADR3425), I had taken…
