  • RE: ADA4522 Drift

    Hello Emman,

    For one of my project (designing a low drift voltage source), I have the same question as Ben.

    I know that this post is pretty old, however, have you published the results of the characterization of the long term drift of the ADA4522 ? Would…

  • ADA4522-4 apparent crosstalk and short-circuit input


    I'm using an ADA4522-4 as a buffer and amplifier for a simple current sense circuit and I observe a strange behavior where one inputs starts to sink a lot of current when another amplifier saturates. 

    My circuit consists of a 330kΩ sense resistor…

  • ADA4522


    I want to use the ADA4522 as follows:

    - Positive power supply connected to ground.

    - Negative power supply connected to -50V.

    Will it will work?


  • RE: ADA4522 feedback resistance

    Hi seekyong,

    When you ask about "increasing the ADA4522 feedback resistance", are you concerned about output current or output voltage swing with your lowest feedack (i.e. 2.94kohm)?
    I think you won't have any issues with such values as Figure…

  • RE: ADA4522 feedback resistor

    Hi seekyong,

    I think you're referring to ADA4522 datasheet Figure 75 where a finite feedback resistor (instead of a direct short) is used for a buffer configuration.

    I don't think you'd need to worry about excess input current flow (due to the input…

  • ADA4522 internal oscillator


    My customers are suffering from 124MHz and 63MHz unwanted radiation appearing on the board.
    My customers are exhaustively checking the device's internal oscillator on the board.
    If you have any material that reassures my customers about the ADA4522…
  • ADA4522-4 in a severe EMC environment

    I have an EMC client using chains of ADA4522 op amps. The input sweeps from 20 KHz to 300 KHz. Sometimes the outputs become slew rate limited. I am concerned the ADA4522 is susceptible to large signal triangle waveform harmonic products causing aliasing…

  • ADA4522-2作为电压跟随器使用,怎么输入电压小于3.6mv的时候,输出是3.6mv,只有输入电压高于3.6mv的时候,现象才对?


  • ADA4522 voltage follower config with dual supplies

    using an ADA4522 (dual pack) for a buffer/inverter setup.  so, one of theamps setup as typical volt follower, the other a inverting amp.  BOth are driven from an AD8221.

    The AD8221 is outputting a 20KHz sine biased at 2V.  Vpp on sine = 2V...
