• How do I map the ADA4841 spice model pins to device actual pins

    I'm trying to simulate with Pspice, however, the symbol has pins 100 to 106. How do I map to actual pins?

    This is the top of the SUBCKT file

    .Subckt ADA4841 100 101 102 103 104 106
    *#ASSOC Category="Op-Amps" symbol=opamp_6_pd

  • 利用ADA4841-2,但輸出無法達到軌對軌

    小弟利用ADA4841-2,VS+為5V,VS-為GND,當輸入電壓大於4.3V以上時,輸出只能到4.3V;當VS+為6V,輸出就可以突破4.3V,

    這樣不就沒有軌對軌功效了,難道還是有0.7V的壓降嗎??

    附件是我參考的電路,麻煩各位高手幫我解答一下,謝謝

    另外,我是利用AD8031做REF的穩壓,利用ADA4841-2做輸入端的穩壓,用以實作AD7685的16bits ADC量測,線路接法皆是參考AD7685的datasheet,

    因此發生上述的問題,還有個疑問,當輸入端電壓沒有接任何東西…

  • ADA4841-2 管脚IN+,IN-一直有电压是什么原因?

    在给ADA4841-2通电后,IN-和IN+无输入信号情况下,两脚都有电压,而且输出脚也有电压,电压在4V左右(电源电压为正负5V),这是什么原因?

  • 使用ADA4841-2作为AD采集驱动时偏置电压有4V多,为什么?

    数据采集A/D采用AD7980,根据数据手册建议采用ADA4841-2作为输入驱动,但现在的问题是ADA4841-2的输入端电压偏置为4.17V(未接任何输入的情况),导致根本无法输入模拟信号(0~5V)。求教各位专家。

    已经做了一下实验:(1)单独给ADA4841-2上电(板子上无其他任何器件),(2)断开后一级,即与AD7980断开连接,输入端的电压为4.17V左右,输出为4.9V多。

    另外,将-Vs接到地也是同样的情况。被这么个AD驱动折磨死了。

  • wants to confirm whether LT8708-1 (LT8708EUHG-1#PBF) can work independently.

  • AD9523-1  Can I precisely adjust output clock frequency with AD9523-1 (EVAL-AD9523-1)?

    Greetings!

    I would like to inquire if it is possible to achieve precise frequency control with EVALZ - AD9531-1? I'm interested in generating a clock signal that is a multiple of femtosecond laser output pulse rate, which can be something close to 80…

  • HMC666_using IF pin without 1:1 transformer

    Hello Team.

    1:1 transformer applied in IF pin is expensive.

    so we want to use without transformer.

    is it possible that?

    Can you support solutions?

    thanks.

    Best regards,
