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
