• AD8137 input transient tolerance

    We have a DO-160 lightning protection circuit for the input pins to the AD8137. We can clamp the voltage at 9V for 300ns. We are operating at +-5V rails. The datasheet abs max is +-6V.

    I expect the part will survive the transient. Has there been any analysis…

  • 14bits DAC and AD8137

    The differential output of the DAC5672A is -1V to +1V, and it is expected to be amplified to -5V to +5V. Ask questions that are magnified later: such as attachments
    1. Is the match between the DAC and the differential op amp correct? Is R45 needed?
    2. How…

  • AD8137 not generating differential output.

    Hello everyone, My problem may be silly and this is because i am very much new on analog device mostly on lab practice. I am using the AD8137yrz model differential amplifier to generate amplified and differential signals. First I did the spice simulation…

  • AD8137 getting hot when power on


    I am using AD8137YRZ to convert single-ended input to differential output. After power on, the AD8137 is gatting hot. The AD8137 was oscillating. After removed the capacitor C620 and C621 on the feedback loop, the oscillating is gone. However…

  • MFB Antialiasing Filter Problem AD8137/ADA4932

    Hi all,

    I created a lowpass 3-pole Antialiasing Filter in MFB fully differential Topology to drive a differential ADC. The cutoff frequency is 30kHz and the Gain is 11.

    When I use the AD8137 for the filter the output of the AD8137 is oscillating at…

  • ad8137 how to remove large common-mode signal?

    How can I remove a large common mode signal from the differential input of ad8137 while maintaining the high gain-bandwidth prroduct? In my particular case the common mode signal is +-12V at 20-50 kHz. Thanks for any advise, Tom

  • AD8137 Output when gain is 1 (unity).

    In case of AD8137 differential amplifiers' simulation, I have problem to understanding the output behavior. The input and feedback resistors value is 1 KOhm. Therefore I suppose to have gain 1 and which leads the output voltage as like input voltage.…

  • AD8137 impedance matching for a very low impedance source

    I am attempting to impedance match a LC network as shown in the attached schematic. Using the ad8137 in differential mode, does the input need to be impedance matched in the first place when attached to a very low impedance source?

  • ad8137 small sig. bw of 76MHz and large sig. bw of 110MHz


    I am studying AD8137 and have some questions.

    On AD8137 datasheet it says that small sig. bw is 76MHz and large sig. bw is 110MHz.

    I am wondering why when inputs are small signals, the bandwidth is smaller...

    Thank you.
