• AD8022


    I am using AD8022 as non-inverting unity gain buffer in my circuits. However when I powered the circuit I surprised to find that the IC was running in warm condition.Is this normal? or the device is not unity gain stable. Please advice.


  • AD8022 Output oscillating


    In the below configuration AD8022 output swings like in the waveform.

    Can anyone suggest what would be the problem?

  • AD8022 spice model noise problem

    I've designed a 5th order low pass antialiasing filter using the filter wizard. The design I obtained is based on the AD8022 dual opamp. I've constructed the circuit and the result I got today are alright.

    I also need to model the circuit using…

  • AD8022, input impedance 20k ohm


    I have following questions on AD8022.

    a) Datasheet shows, INPUT CHARACTERISTICS, Input Resistance (Differential) is 20kΩ, as Typical.

    Could you please confirm whether this value 20k is really correct or not ?

    It may sound strangely, but normally…

    Hi, Steven.

    I attached the AD8022 and ADA4857 SPICE models. These were recently created and tested. The models available in the web were not yet updated thus the results were not very good. The attached models are better so use them instead.


  • Differential input voltage of opamp ±0.8 V


    In AD8022 datasheet has Differential Input Voltage  ±0.8 V at absolute maximum rating.

    In design i provided the supply voltage as  +/-12V.

    i used the amplifier as Voltage follower,inverting amplifier and active filter.

    Inverting Amplifier and Filters…
