• ADA4665-2失调电压问题

    我一直在用ADA4665-2,现在遇到一个小问题,之前测试的信号是0~5V、0~10V的电压信号,此芯片的应用一点问题都没有。并且我也做过实验,用ADA4665-2只作为信号跟随时,其失调电压的确很低,进入ADC后,最低能识别到0.2V左右。但是如果我要测试的信号范围变为20~40mV时,在跟随后,再加一级放大的话,效果就不是很好了,是不是因为我采集的信号范围和运放所加的电源(0~10),导致被测信号落入失调电压范围内,或是接近失调电压造成的?

    我还要问两个问题:

         1.如果将电源电压变为正负电压…

    Hello

    I have a question about AD4655.

    Although there is description that the typical value of the slew rate of this device is 1V/μs, please tell me the upper and lower limits.

    I could not find it in the datasheet.

  • ADI年度贺岁片——ADA4665-2放大器的应用

            以前基本以数字电路为主,换了工作后,逐渐增加了模拟电路的设计,但是通过在ADI的学习和了解,这些也不是什么问题了,从简单的放大器应用,到放大器的特殊应用,基本上都有所了解了。之前利用AD4665-2做了一个数据采集放大电路,其轨到轨、低功耗和最低阈值很好的解决了我的特殊问题,随后又将其应用到电压基准输出电路,更是淋漓尽致的发挥其作用,ADI的芯片的确是很给力~~~

  • RE: Script file of ADV7611 for 24bit SDR 4:2:2 Mode 2 output

    Hi,

       In general the drive strength and trace impedance must match to reduce ringing

      The ringing is caused by a mis-match in the drive strength and trace impedance.  Try lowering the drive strength for the pin output or increasing the series resistor.Note…
