ADXL1001 Damaged / Electrical Spikes

Category: Hardware
Product Number: EVAL-ADXL1001Z

Dear Analog,

I have been using for quite some time the Analog evaluation board EVAL-ADXL1001Z for the accelerometer ADXL1001.

I have been facing issues, 2 boards are damaged (not outputting any acceleration reading) and 1 board now is producing some random spikes during reading of acceleration.

Vdd = 5.000V (regulated to 0.1%, no overshoot during turn on/off)

Accel = 1 to 50 g0-pk at 1.3kHz

Sampling Freq. = 48 kHz.

Could you please help me figure out what could possibly be happening to the boards?

Thanks.

  • Hi, 

    sorry to hear that the evaluation board is not working. Can you please share the turn on waveform, just to confirm there is no overshoot at all. It sounds like the boards have been electrically damaged. 

    When you say there is no outputting any acceleration, do you mean the output reads Vdd/2 or 0V ? 

    Regards, 

    Pablo.
