Hi I want to make a simple circuit with ADXL103 but I have no idea what the pin 3, labelled COM is for ? I have searched the internet but I seem to get results with credit card pin number tutorials :???: so excuse if its a simple way around this, but I seem to be unable to find the answer ?
Do you connect it to GND ?
 

Yes, It has to be connected to the Ground.It is mentioned in the block diagram in Datasheet. I think that is the only Ground pin the Chip has.
