• ADXRS646-EP Datasheet Figure 6

    Reference: Figure 6 of, ADXRS646-EP part datasheet.

    We understand, Null Bias is ratio metric to Vratio input.

    For Vratio of 6V, Null will be 3V(Typical). But in the graph (Vratio is mentioned as 5V) and Null bias is still 3V.

    As per our understanding…

  • ADXRS646

    On page 10 of the datasheet under "Modifying the measurement range" it states that "The ADXRS646 scale factor can be reduced to extend the measurement range to as much as ±450°/sec by adding a single 225 kΩ resistor between RATEOUT and SUMJ." What value…

  • ADXRS646

    Hello there, one of my customers has designed in the ADXRS646 inertial module.

    Find below an excerpt of the schematics. It looks like there is a small mistake in the design.

    Looking at the RATEOUT signal: 6V/(11.5K+17.4K) = 207uA current drive.

  • ADXRS646 calibration

    Dear All.

    I have an application in which I have to measure the angle between a couple of rotating planar surfaces around a common joint.

    Just for giving you a picture, imagine you have to open a book and measure the angle between the two rigid covers…

  • ADXRS646 drift calculation

    How does one calculate the output drift for the ADXRS646? There are 2 factors given on the datasheet, i.e. the 12deg/hr and the 0.01deg/sqrt(sec). How do these factor into the calculation? Do you sum the drift due to each?

  • ADXRS646: AQEC qualification data

    The ADXRS646 product page says that ADXRS646 is AQEC qualified and the
    qualification data can be had on request. how do I request this data?


    This is an error, it was intended originally to qualify this part to AQEC but
    this was…

  • ADXRS646 Null Output Over Temperature

    Hi there,

    I'm working on a system which uses the ADXRS646-EP to measure the rate of rotation about one axis in a vehicle.  We have a circuit to cancel the null output which we tune during production, such that the system output is zero for zero rotation…

  • Power supply for ADXRS646

    Can the ADXRS646 be run from a lower voltage than 6V, with perhaps somewhat decreased performance?  In particular could it be run from 5V supplies, with perhaps slightly decreased range and/or sensitivity?  If so, what would the specific trade-offs be?
