Surface Mount
Micromachined Accelerometer
The MMA series of silicon capacitive, micromachined accelerometers features
signal conditioning, a 4-pole low pass filter and temperature compensation. 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.
