Low-g
Micromachined Accelerometer
The MMA series of silicon capacitive, micromachined accelerometers feature
signal conditioning, a 2-pole low-pass filter and temperature compensation.
Zero-g offset full scale span and filter cutoff are factory set and require no
external devices. A full system self-test capability verifies system functionality.
Features
• Integral Signal Conditioning
• Linear Output
• 2nd Order Bessel Filter
• Calibrated Self-test
• EPROM Parity Check Status
• Transducer Hermetically Sealed at Wafer Level for Superior Reliability
• Robust Design, High Shock Survivability
• Qualified AECQ100, Rev. F Grade 2 (-40°C/+105°C)
Typical Applications
• Vibration Monitoring and Recording
• Appliance Control
• Mechanical Bearing Monitoring
• Computer Hard Drive Protection
• Computer Mouse and Joysticks
• Virtual Reality Input Devices
• Sports Diagnostic Devices and Systems
