• AD8021 distortion

    Hi,

    When I drive my AD8021 with signal higher than ~300mV my output signal (sine) starts to distort. Without the compensation capacitor I can input larger values before the distortion starts, but when it then starts it seems more severe. I have work…

  • VGA with AD8021 ?

    I need to amplify signal up to 1MHz sine, amplitude 10uV - 1V from sensor for ADC 16bit.

    The decisive factor is the amplitude and phase.

    In other words, I need an amplifier with switchable gain 1x,10x,100x,1000x.

    Because we did not find a suitable…

  • AD8021 thermal layout

    I am working on a circuit where the AD8021 will be driving a 300 ohm load at about 20V p-p .

    To dissipate power, I want to make some of the PCB traces very large.

    check my reasoning:

    +in and -in should not be made large because stray capacitance on…

  • RE: Noise Analysis of AD8021 in LTSPICE

    Hi Ajith,

    I've heard back from folks in charge of AD8021 macromodel.

    They have updated the pspice macromodel of AD8021 to correct for the noise discrepancy you had pointed out. They will also update the web site with the updated model.

    Thanks for…

  • AD8021 spice model issues

    Hi

    I downloaded AD8021 Spice model from Analog website and simulated the OpAmp alone and it worked fine. When I put AD8021 model on my Power Amplifier circuit , it crashes and I am not able to see the simulation. I have changed different parameters in…

  • AD8021 output offset

    Hi,

    I have a significant DC offset at the out of the circuit.

    Could anyone explain the reason for this ...

  • AD7676 with AD8021 drivers

    We have a telemetry deck that uses AD8021s as a single-ended to differential driver for an AD7676 PulSAR ADC as documented in the AD7676 data sheet.  We want to make sure that when using +/12V supplies for the AD8021s, their inherent current limiting is…

  • Evaluation board for AD8021

    Hi,

    I need to test AD8021. Could you suggest me a suitable evaluation board, please?

    Waiting for your kind reply.

    Thanks very much

    Best regards

  • AD8021 Spice Model Problem

    HI Engineerzone,

    I am a test development engineer here also in ADI. I would like to raise a question about the LTSpice model of AD8021, We are planning to use AD8021 as a unity gain single ended to differential amplifiver for a 10V, 150MHz input sine wave…
