Hi,
I have an accelerometer whose output range is -5V to +5 V. Is it possible to read this voltage using Arduino Mega.
The accelerometer is PCB 352A56. The link to the datasheet for this particular accelerometer: Model 352a56 | PCB Piezotronics (en)
Where does it say +-5v? It looks like some sort of current loop to me.

THE SENSITIVITY IS 100Mv/G AND THE RANGE IS +-50G. sO THE OPERATING VOLTAGE WOULD BE +-5v.

I am thinking of using the digital inputs and use an ADC along with it. Dos this make any sense? Or is there anykind of offset mechanism?
Thanks

Can anyone please suggest an ADC with +-10 V input range and SPI protocol which would work with Arduino Mega??
The electronics within ICP accelerometers require excitation power from a constant-current regulated, DC voltage source.
From Wikipedia.
The data sheet mentions this as well.

I have signal conditioning device with the accelerometer. It gives the required current to the accelerometer. The output of this signal conditioner is +-5V. I am not sure about the output current though. The max impedance is 200ohms.
LTC1859, 8 channels though.

Thank you so much.
Any input if using an ADC will solve my purpose?

Sorry, not sure if that's a question or what.
