Surface Mount
Micromachined Accelerometer
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.
