• AD8022 Spice Noise Model

    Is there an update for the AD8022 spice model that fixes the noise? The model on the website shows the opamp having hundred's of nV per rtHz noise. This issue was brought up in 2017:  AD8022 spice model noise problem but it seems the spice model on the…

  • AD8022 Output oscillating

    Hi

    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

    Hi,

    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…

  • AD7266 driver circuit

    Hi

    I have inherited a design in which an AD7266BCPZ is driven by an AD8629 op-amp.

    the AD8629ARNZ uses a chopper architecture, and is bot suitable , to my understanding, for unbuffered SAR driving.

    some oscillation were measured on the amp output (it…

  • RE: Filter Wizard / SPICE noise analysis inconsistency

    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.

    Regards…

  • RE: Differential input voltage of opamp ±0.8 V

    HI Selva,

    If you are using the AD8022 as an inverting amplifier as shown below, I don't think you gonna have a problem with the absolute maximum differential voltage. The differential voltage on the abs max rating refers to the difference of voltage…
