Micromachined Accelerometer

The MMA3202 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.
