Micromachined Accelerometer
MMA1200KEG
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.
