Notes:
1: Specifications apply and are characterized up to ±1g range. The accelerometer is capable of supplying acceleration information up to ±30g but at a reduced accuracy
2: Scale factor shown in mA/g as a standard. If you require scale factor in volts/g, please specify voltage range when ordering.
3: Voltage output via customer supplied load resistor
*Specifications subject to change without notice on account of continued product development.
