• 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)?

  • AD4000 reference voltage and power consumption

    Hello,

    A couple of questions about AD4000 design:

    It is a 1.8V device; however, the current consumption is not mentioned anywhere in the DS (or I am not looking hard enough). On page 6 of datasheet, power dissipation numbers are given for different sampling…

  • 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…

  • 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。

    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…

  • 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.

    Regards,

    John…
