ADIS16405 - bias tempco, supply sensitivity

Question asked by rogerfr on Mar 19, 2015

Dear All,

I am trying to make a mathematical model for ADIS16405.. My problem is BIAS TEMPERATURE COEFFICIENT and BIAS VOLTAGE SENSITIVITY...

How do I handle these two constants?

 

1. BIAS TEMP COEFF.

Bias Temp Coeff of ADIS16405 is +/-0.01 deg/sec/C

what does this +/- mean?

 

Reference temperature is 25 C

Assume I am using the imu at 15C for 10 min.s

 

Error = (25-15) x (0.01) x (600) = 60 Degrees?? ???

 

2. BIAS VOLTAGE COEFF.

Bias Voltage Coeff of ADIS16405 is 0.32 deg/sec/V

Nominal Voltage is 5.00 V

 

Does this mean:

 

2.1 If my power source is 5.25 V

for again 10 min of run

 

Error = (5,25-5) x (0.32) x (600) = 48 degrees ????

 

2.2 If my powe source is 4.75 V

 

 

Error = (4.75-5) x (0.32) x (600) = MINUS 48 degrees ????

 

 

Can you please help in this error calculations

 

Regards
