From the ADXL326 data sheet: current consumption 300uA ...
I'd use a resitor (say 1.5k) followed by a zener diode (between 8 and 12V) and then 3V linear voltage regulator with typicalllly associated components such as input/output capacitors ..

Yes, it's a microphone input, typical signal levels are mV up to 100 mV. Very surely you don't have a problem of needing amplification.I'm thinking it might be because there is some standard for it, and thats the reason they dont write it in the manual or tech notes.
From this link it looks like Line In is 3.5V peak-to-peakYes, it's a microphone input, typical signal levels are mV up to 100 mV. Very surely you don't have a problem of needing amplification.
Microphone isn't line level. A microphone input usually won't be able to process line level without overload respectively signal distortion.From this link it looks like Line In is 3.5V peak-to-peak
The datasheet says NC pins 1 and 9 can be connected to ground.I only need to connect 1 to ground as they propose in the datasheet?
