Hi,
I am using ADXL326 EVK in my designs to measure the acceleration of an Actuator. For the verification, I tried to use the other accelerometer ADXL325 to get G peak values. Strangly observed totally different results.
As per the datasheets ADXL326 requires, Vp-p/2*57 and ADXL325 requires Vp-p/2*174 to get the G peak values.
In my system, using ADXL326 measured as 625mV p-p and ADXL325 measured as 1140 mV p-pso, the effective Gpeak values are 5.48 and 3.27 respectively.
Both the chips are operating with 3V supply.
Here are my questions:
Why I am seeing the different G peak values?
Is there any way I can measure 1G/2G/3G for calibration?
Do you recommend any system available in market to get the calibration?
Thank,
Sree
