• AD8226 Output

    Hi

    For verifying AD8226(Instrumentation Amplifier) functionality a general purpose PCB is made.

    Below is the circuit for AD8226

    44 ohm resistor is internal sense resistor in AD5420 (Between R3sense and BOOST). AD8226 is interfaced to AD5420 in current…

  • AD8226 Supply Current

    Hi

    I'm using AD8226 in my design. I'm providing 31V(VDD) and -4V(VSS) for AD8226. What is the supply current current required by 31V and -4V power rail. I'm asking this question as supply current for only some supply values mentioned in datasheet.…

  • AD8226 offset voltage

    Hi

    I've selected AD8226 in my design for self diagnosis of 0-20mA current loop.

    I simulated AD8226 for sensing a constant current 1mA across 40E resistor. Below is the result for same…

  • AD8226 gain problem

    I have a gain problem when i am testing my ad8226.

    The test circuit is shown below in picture.

    When Vin increases, the gain decrease from 330 to 315。

    However, I test the same circuit with ad623, the gain is stable. The only difference is  that I remove…

  • AD8226: automotive grade?

    Hello,

    I'm wondering if the part AD8226 is qualified to AEC-Q100.

    Where can I see which parts have been qualified to this? Is there a selection guide?

    Thanks a lot!

  • AD8226 filter circuit

    Hi

    I was referring to MT-070 to ad filter circuit to AD8226.

    ...

    IOUT_ AD5420 and IOUT_ AD5420_R are two terminal of resistor in a 4-20mA current loop where I'm sensing. As HART signals also flows through my 4-20mA loop, Is there any dependency while selecting…

  • Supply limit in AD8226

    Hi

    Equation 1 in AD8226 is

    Vcm – mod (Vdiff*G/2) > -Vs + V-limit

    Vcm= 23.6V

    Vdiff = 0.8V

    G = 1

    Vref = 0 in my application leading to

    23.6 – mod(0.8*1/2) > -Vs + (-0.55)

    23.2 > -Vs-0.55

    23.75 >-Vs  @ -40C

    @+125C

    23.2>-Vs-0.0…

  • AD8226 - GAIN Error

    Hi,

    I would like to know the Gain variation (of AD8226-BRZ) with respect to Input differential voltage frequency for a gain setting of 1. The data sheet says 0.01% of Gain Error along with a Temperature coefficient of 2PPM/degree C. My application needs…
