Data Sheet: Technical Data
MMA3221KEG
Rev 1, 11/2012
Surface Mount
Micromachined Accelerometer
The MMA3221 series of dual axis (X and Y) silicon capacitive,
micromachined accelerometers features signal conditioning, a 4-pole low
pass filter and temperature compensation and separate outputs for the two
axes. Zero-g offset full scale span and filter cut-off are factory set and require
no external devices. A full system self-test capability verifies system
functionality.
Features
• Sensitivity in two separate axes: 50g X-axis and 20g Y-axis
• Integral Signal Conditioning
• Linear Output
• Ratiometric Performance
• 4th Order Bessel Filter Preserves Pulse Shape Integrity
• Calibrated Self-test
• Low Voltage Detect, Clock Monitor, and EPROM Parity Check Status
• Transducer Hermetically Sealed at Wafer Level for Superior Reliability
• Robust Design, High Shocks Survivability
• Qualified AEC-Q100, Rev. F Grade 2 (-40C/ +105C)
Typical Applications
• Vibration Monitoring and Recording
• Impact Monitoring
• Appliance Control
• Mechanical Bearing Monitoring
• Computer Hard Drive Protection
• Computer Mouse and Joysticks
• Virtual Reality Input Devices
• Sports Diagnostic Devices and Systems
