• ADG412: Lower voltage supplies than specified

    Q 

    Can switches and multiplexers be operated  with logic power supplies less than
    those specified in the data sheet, eg. with 3.3 volts.

     

    A 

    Specifically the ADG412 is specified from 4.5 to 5.5V i.e. 5V +/-5%. If you go
    outside this range then…

  • Offset: Temperature Coefficient total in PGA using AD797 and ADG412

    Hi all:

    Do anyone know how the calculation of the total temperature coefficient show in "Analog Device" literature of PGA, using AD797 and ADG412, increases from 0.6uV/ºC to 1.6uV/ºC? There is a 1uV/ºC part, not belonging to the AD797B, I am not able…

  • ADG411: is ist possible to worf with a 3V Logic Level?

    Q 

    I want to use the ADG411 +-12V but with a Vlogic=3V - would this work?

     

    A 

    Yes it is possible to apply 3V to the Vl pin. We just have it specified at 5V.
    For the ADG412 the Vl applied can be in the range of -0.3V to Vdd +0.3V.  Our
    parts…

  • ADC的误差

    大家好！   

         最近看了《ADI模数转换器应用笔记，第一册》里面的AN-282：采样数据系统基本原理一节，里面讲了很多有关有效位数，噪声方面的内容，但我在实际的电路中发现，影响AD精度的原因主要是参考源和采样保持，如果选的参考源很好的话AD精度就会提高，外置的采样保持器往往比AD内部的采样保持器要好。

         我的问题是：ADC的所有误差都有哪些？有没有这种讲所有误差并且有公式的资料没？我想计算下，再和实际的电路结果对比下，看看哪里可以改进。谢谢各位大牛！
