Hi everybody,


I am currently developing tiny sized IMU measuring kit. I am using ADXL345 as accelerometer.

I have tried to read/write ADXL by I2C without powering it. Due to my PCB bug, power power supply of ADXL345 was not there although ground is connected.


So I was wondering could it effect ADXL345 (IC silicon)? Is there any documents related with this kind of issue?
