SEMICONDUCTOR TECHNICAL DATA
Surface Mount
Micromachined Accelerometer
The MMA3200 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.
