Dual-Axis SPI Inertial Sensor
MMA65xx, a SafeAssure solution, is a SPI-based, dual-axis, medium-g, overdamped lateral accelerometer designed for use in Automotive Airbag systems.
Features
• ±80g, ±105g or ±120g full-scale range, independently specified for each axis • 3.3V or 5V single supply operation • SPI-compatible serial interface • 12-bit digital signed or unsigned SPI data output • Independent programmable arming functions for each axis • Twelve low-pass filter options, ranging from 50 Hz to 1000 Hz • Optional offset cancellation with > 6s averaging period and < 0.
