Hi, We found a serious problem about  ADIS16467-1BMLZ:

When angular rate over 200 deg/sADIS16467-1BMLZ’s Gyro output will reverse and jump to opposite side!

We have four ADIS16467-1BMLZ,and all of them have the same problem!

And we also have some ADIS16460AMLZ ,we test ADIS16460AMLZ and ADIS16467-1BMLZ in the same condition,the ADIS16460AMLZ is all right.But all of the ADIS16467-1BMLZ has the”output reverse over 200 deg/s”problem.

The Evaluation Boards and software that we used are list as blow:

1EVAL-ADIS2Z

2ADIS16IMU4/PCBZ

3IMU EVALUATION SOFTWARE(v1.18.9)

The test input signal is 2Hz~3Hz  SIN singal ,just like the following figue:

The following figue is The ADIS16460AMLZ’s correct responds  ,when angular rate over the +max range or –max range,the gyro’s output will keep it’s max output until angular  rate fallen back in gyro’s Dynamic Range.

The following figue is ADIS16467-1BMLZ’s problem: When angular rate over 200 deg/sADIS16467-1BMLZ’s Gyro output will reverse and jump to opposite side!

Please tell me how can I solve this problem?
