• AD8041/AD8041S Input Impedance/Bias/Resistance

    I have an application for a rad-hard op-amp that is very sensitive to input impedance / input bias / loading, so I have a few questions about the AD8041 and AD8041S.

    1. In the AD8041 datasheet, it states that the input resistance is 160 kohm (with a…


    Absolute maximum rating of opampAD8041 is 12.6V as per datasheet and operating range of power supply is given as 3V to 12 V in  mode.

    I am using AD8041 OPAMP in dual supply Vs=±5V. Does this mean Iam operating the opamp at 10V and device is operating close…

  • AD8041S Protection Diodes

    I am wondering if a powered down (i.e. Vsupply = ~0 V) AD8041S can be exposed to small amounts of input voltages on one (or both) of its input pins. Assuming that the input pins have >1kohm in series, so any current flowing into the pin would be limited…

  • SPICE model of AD8041

    Unfortunately, the disable node of the AD8041 is not implemented in the SPICE model.

    Is there a serious reson for that? Could this please be added to allow proper simulation?


  • AD8041 Radiation tolerance test data.

    Where can I find radiation test data (High dose report, low dose report and
    heavy ion test data) for AD8041? 


    Low dose and high dose radiation reports for AD8041 are available on our
    website at the following web pages:

  • AD8041 :No connect pins

    I'm using the following amplifiers in a design: AD8041ARZ, AD524BE, OP284FSZ.
    I'm wondering if it is ok if I connect the nc-Pins (no connect, referring to
    the datasheets) to Signal-Ground. Does this affect the Amplifiers somehow?
  • AD8041 output AC coupling issue

    Dual supply mode opamp in Low pass sallen key lowpass configuration with output AC coupled using a capacitor , current increases rapidly in negative supply. When used with resistor as coupling mechanism in place of capacitor in series, device performance…

  • Why is AD8041 as an unloaded buffer showing an offset?

    I am using an AD8041 opamp for my project.

    Initially I tried using it as an unloaded buffer.The schematic is as shown:

    The waveforms VG1 and VF1 as obtained on an oscilloscope are shown below:

    Waveform VG1:

    Waveform VF1:

    As can be seen,the…

  • Can I tie the NC pins of AD8041S to ground?

    Can you confirm if AD8041SL (5962L9683903VHA)  CFP-10 package  NC pins 1, 2, 6
    and 10 are not bonded to die.
    We wish connect all NC Pins to GND.


    We have reviewed the AD8041SL (5962L9683903VHA) wire bond diagram and I can
    confirm that…
