Low G

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.
