Note 1: Specifications apply and are characterized up to ±1g range. The accelerometer is capable of supplying acceleration
            information up to ±30g but at reduced accuracy.

Note 2: Voltage output via customer supplied load resistor.
Note 3: Scale factor shown in mA/g as a standard. If you require scale factor in volts/g, please specify voltage range when ordering

          *Specifications subject to change without notice on account of continued product development
