• REF43 Trim pin function

    The simplified schematic in the REF43 datasheet shows a resistor divider between the VOUT pin and GROUND pin. There is also a resistance from the TRIM pin to the middle of the resistor divider.

    I want to calculate the worst case output voltage range…

  • Information about REF43NBC Die part

    Is the Lifecycle status for Die part “(REF-43(1802Y)” and the REF43NBC the same?

    Can you please give me the lifecycle status for REF-43(1802Y.

     

    1802Y is the dice’s mask set ID and the part that customers can order is the
    REF43NBC…
  • RE: AD7714 REF IN(+) Current

    Hi,

    Yes, I think the current is around some uA level only. This thread may be able to help you regarding the actual measurement. https://ez.analog.com/message/114854?commentID=114854#comment-114854 

    We also have some recommended voltage reference parts…

  • DC Voltage Calibration Sources for the ADALM1000

    Just how good are the voltage measurements you make using USB based instruments such as the ADALM1000 or Analog Discovery? How would you find out? You could always check the readings against a bench DMM but a good DMM can cost hundreds of dollars. Instrument…

  • 工业应用Sigma-Delta ADC常见问题解答

    问题:峰峰值噪声与有效噪声的区别,峰峰值分辨率与有效分辨率的区别?无失码分辨率又是指的什么?

    答案:无失码分辨率是对ADC线性性能的评价指标。峰峰值分辨率和有效值分辨率是评价ADC噪声性能的重要指标。它们之间的关系是

    峰峰值分辨率=有效分辨率-2.7 bits

    这个关系的理论基础是,噪声通常是随机的,并且它的分布是正态分布。那么

    Vnoise (peak-to-peak) = Vnoise (rms) x 6.6;99.9%的出现概率

    如果转换为分辨率,就是2.7位的差别。(log26…
