Hi, This is urgent for us because it is holding up a prototype. We are in the final stages of designing our in ear accelerometer and want to confirm a few things.

1. Do we need to supply voltage to both voltage pins on the chip, pins 14 and 15?

2. Do we need to ground both ground pins on the chip, pins 6 and 7?

3. Do the specs off of the datasheet include your testing with the recommended capacitor, for clarification if I do not add a capacitor on each axis how much noise should I expect?

4. The sensitivity appears to be 0.5% for one axis and 1.4% between two axis? 

Many Thanks,
