Surface Mount

Micromachined Accelerometer

The MMA series of silicon capacitive, micromachined accelerometers

features 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
