• ADG412: Lower voltage supplies than specified

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

     

    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?

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

     

    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!
