Technical Data
Surface Mount
Micromachined Accelerometer
The MMA series of silicon capacitive, micromachined accelerometers feature
signal conditioning, a 4-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
• 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
Typical Applications
• Vibration Monitoring and Recording
• Impact Monitoring

ELECTRO STATIC DISCHARGE (ESD)
WARNING: This device is sensitive to electrostatic
discharge.
Although the Freescale accelerometers contain internal
2kV ESD protection circuitry, extra precaution must be taken
by the user to protect the chip from ESD. A charge of over
2000 volts can accumulate on the human body or associated
test equipment. A charge of this magnitude can alter the
performance or cause failure of the chip. When handling the
accelerometer, proper ESD precautions should be followed
to avoid exposing the device to discharges which may be
detrimental to its performance.
