• ADR381 output capacitor ESR

    Please could you tell me if there is a limit on the value and/or ESR of the
    capacitor connected to the output of the ADR381. Are there any possible
    stability implications of using low ESR ceramic capacitors (10 uF X5R)?

  • RE: AD7780 non-ratiometric usage

    Hi Kevin,

    The input range is defined by Vref. So, with a 2.5V reference, the input range is +/-2.5V/gain which equals +/-19.5 mV. If you are using an absolute reference, a low-noise reference such as the ADR381/ADR391 should be used.

  • RE: about the noise density of voltage reference IC.

    Hello LucaV,

    Thank you for your reply.

    I understood that the voltage noise density is flat at higher frequencies.

    I'd like to know the  noise density of ADR361 and ADR381.

    Do you have the chart as same as ADR391's?.

    Regards,
    Kou

    Hi cevdet29,

    The AD7794 suggests the use of ADR391 and ADR381 which are 2.5 V micropower low noise voltage reference.

    For 3.3V, I suggest you use the ADR4533…

  • RE: AD7794 intead of ADUCM360

    Hi cevdet29,

    The AD7794 suggests the use of ADR391 and ADR381 which are 2.5 V micropower low noise voltage reference.

    For 3.3V, I suggest you use the ADR4533 which is ultra-low noise but has Is=950uA compared to the ADR391 with Is=120uA.

    Yes you can connect…

    Hi..

    apologies. I was just putting the result which i got during testing of ad7193 not targeting precision measurements.

  • RE: AD7788 increase the input range

    Hi Ocela,

       As mentioned on the AD7788 datasheet it can have a unipolar and bipolar ranges. The Ain+ input can be referred to the Ain-. As an example, when using 2.5V on Ain-. The input voltage range is from 2.5V to 5V but when it is in bipolar mode the…

  • RE: AD7193数据读取

    您好,

         1. 从硬件的角度看,没有看出问题,提一点建议把ADR381的输入电压接到模拟电源处。

         2. 能否贴一下发送40个1的spi波形图(CS CLK MISO MOSI),能否贴一下读其它寄存器错乱的波形图。

         3.从上面的波形图看,MISO信号有点问题,边沿很缓。

  • What is the expected voltage range on the 2.5 V output on the ADALM1000?

    I have been using the ADALM1000 to work through the labs in the Engineering Discovery set.  While doing the first two Class A amplifier labs I noticed my output is not centered around 2.5 V as per the reference voltage used but rather just under 2.4 V…
