The datasheet for the ADA4841 says that the exposed paddle of the LFCSP package should be connected to ground (Figure 3 on first page).  In a split supply design is that Ground (0V) or is it the negative supply?

I am trying to use ADA4841 spice model in LTspice and also in Spectre. In both cases the results are corrupt. The output node shows -0.6V while VEE is at GND. I amk suspecting the model is corrupt

Does anyone have the previous release of this library…

I am laying out a board based on the ADAU1452.This is the eval board for the DSP. I cant find a spice model for the ADA4841-2YRZ. This is my first time laying out a board. I have the dash 1 part in my data base. But can't seem to get the model for the…

Hi there,

I'm building a precision voltage generator and I'm using a DAC to drive the ADA4841 which is in a voltage follower configuration.

Previously it was the ADA4807, but it had some issues like: powering the unit from the USB and batteries…

HEllo,

I am planning to use the ADA4841 to drive the AD7980 and am having trouble finding the input current range of this amp.  Is it 10nA to 10uA?

Thank you,

Frank

I have asked a related question here in ADC section: Unstable, voltage reference of AD7682/AD7689

But I think it may be more appropriate to put the question here.

I am using ADA4841 to buffer a voltage reference. The ADA4841 is powered with +5V and…

小弟起初在ADA4841-2的輸入端+IN跟-IN沒有接任何東西，當輸入端沒接電壓時，量到的是4.3V左右，

之後在輸入端+IN跟-IN兩點並上10K電阻，當輸入端沒接電壓時，量到的是則變成0.03V左右，但它仍然沒辦法達到軌到軌，

參考電壓在5V情況下，輸出電壓仍然只有4.3V。

AD的專家們，麻煩幫忙一下，這問題困擾好久了，而且在datasheet上好像沒有說要在輸入端+IN跟-IN兩點並上電阻，

該怎麼處理比較好呢??，謝謝大家的幫忙!!

我采用ADA4841运算放大器作为mos管驱动电路做了一个恒流源电路(见附件，J5和J6分别为未知电阻)，但是在实际的使用时发现当R18的阻值过大时，例如1.1MΩ时，运放的输出端为0.

当减小R18的阻值时，例如50KΩ时，运放输出正常。我的理解是我选择的运放输入阻抗偏小，不知我这样理解是否正确，另外贵公司还有其他其他替代型号可以解决这一问题？如果我理解错误，那么是什么原因造成的，能否告知？

ADA4841最大供电电压是±12V，还是|+Vs|+|-Vs|=12V? 有类似性能但供电电压更宽的型号吗？
