Technical Data
Low G
Micromachined Accelerometer
The MMA series of silicon capacitive, micromachined accelerometers
features signal conditioning, a 2--pole low pass filter and temperature
compensation. 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
• 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
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
