• 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…

  • 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 ...

    Thank you

  • 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…

  • RE: ad8021 output voltage vs frequency

    Hi, 

    Maximum output voltage of AD8021 is not limited to 50mVpp when operated at freqs higher than 50MHz. May I know what application are you planning to use AD8021?

    Regards,

  • 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

  • AD8021 Spice Model Issue

    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…
