±1.5g X-Axis Micromachined

Accelerometer

The MMA series of silicon capacitive, micromachined accelerometers feature

signal conditioning, a 2-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.
