between 20 and 100g may be available upon request
• Full-scale range is independently specified for each axis
• 400 Hz low-pass filter, 0.1 Hz high-pass filter, 4-pole, 16 μs sample time,
additional filter options are available
• Ratiometric analog voltage output
• 10-bit digital signed data output
• SPI-compatible serial interface
• Capture/hold input for system-wide synchronization support
• 3.3 or 5 V single supply operation
• On-chip temperature sensor and voltage regulator
• Bidirectional internal self-test
• Minimal external component requirements
• Pb-free 20-pin SOIC package
• Automotive AEC-Q100 qualified
Typical Applications
• Crash detection (Airbag)
• Impact and vibration monitoring
• Shock detection
