adxrs642 scalefactor

hi

i have an adxrs642 gyro.

i want to increase output of this gyro from 250 deg/sec to 1200 deg/sec. how can i do it?

  • this is our question sent to analog support:

    I interested in buying a gyro with a +-1200 degree/sec measurement range, but i checked all the sensors in the gyro page on the site, i couldn't find a gyro with this measurement range. i consider ADXRS642, and i found in its data sheet that by adding a 225k resistor between SUMJ and RATEOUT i can reduce scale factor to measuring +-450 degree/sec. can i reduce scale factor more than that?

    when i consider the other data sheet, for example ADXRS620, ADXRS610 and ... i couldn't find anything in datasheet according to increasing measurement range. could you please inform me how can i increase measurement rang, and by which gyro sensors i can have +-1200 degree/sec?

    and this is the support answer:

    Dear customer,

    Nice to hear from you! Thanks for your supporting Analog Device.

    Yes, we can increase the dynamic range of the Gyro by setting different scale factor. We offer an application note AN625 to demonstrate this. It takes ADXRS150 and ADXRS300 for example, but it can also be applied to ADXRS62x or ADXRS64x. Please see the attached.
