Micromachined Accelerometer
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.
