ADIS16265 power supply and temperature dependence

Question asked by boksi on May 25, 2014

Hello,

I have some questions regarding power supply and temp calibration of ADIS16265.

In datasheet is stated :

 

Voltage Sensitivity  VCC = 4.75 V to 5.25 V                 0.5  °/sec/V

 

If I have perfect power supply which give exactly 5 V. And gyro is powered up and we measure output.

Suddenly voltage drops to 4.5V . So we will have error in angular velocity from gyro output (angular velocity) of  0.25  °/sec .

Can we calibrate it? Measure voltage, measure angular rate, calculating error and add or subtract from gyro angular velocity output.

 

Same question I have for temperature calibration.

As stated in datasheet :

 

Temperature Coefficient     ADIS16265                   0.005  °/sec/°C

 

Can we measure temperature, measure angular rate and calculate true angular rate?

 

Best Regards,

Borko
