Scale factor shown in mA/g as standard.
If you require scale factor in volts/g, please specify voltage range when ordering.
1: Specifications apply and are characterized up to ±1g range. The accelerometer is capable of supplying acceleration information up to ±20g but at a reduced accuracy
2: Voltage output via customer supplied load resistor
*Specifications subject to change without notice due to continued product development.
