Can accelerometer sensor be defective?

Hi all,

I'm using accelerometer sensor FXLN8361QR1 for my college project. Accelerometer along with signal conditioning block has been mounted on a pcb.

At first accelerometer offset voltage readings at Xout, Yout, and Zout (0.75V,0.75V,0.99V respectively) were consistent with the datasheet, after a couple of days again I tested the pcb, but this time offset voltages at Xout, Yout, and Zout were 1.25V,1.25V,1.57V respectively. The signal conditioning block and other blocks have been checked and verified. I'm not able to figure out this anomaly in voltage readings.

Anybody could suggest me the reason, it would be of great help.

thanks,

Deepak Gowda

Hi Deepak,

First, sorry for the delay in responding, I have been out of the office the last couple of days.

What you are observing is very strange, I have never heard of such a problem. To further investigate it, could you please post here your complete schematic? Did you follow the PCB layout and mounting recommendations described in the device data sheet?

Regards,

Tomas
