Micromachined Accelerometer ± 40g Amplified , IncThe MMAS40G family of silicon capacitive, micromachined Accelerometers
features integral signal amplification, Signal Conditioning a 4pole lowpass
Filter and temperature compensation. ZeroG offset, full scale span and Filter
rolloff are factory set and require no external passives. A calibrated selftest
feature mechanically displaces the seismic mass with the application of a digital
selftest signal.
The MMAS40G incorporates a single polysilicon seismic mass, suspended
between two fixed polysilicon plates (Gcell). The forces of acceleration move
the seismic mass, thereby resulting in a change in capacitance. The Gcell is
sealed at the wafer level, creating a particlefree environment. The Gcell
features builtin damping and overrange stops to protect it from mechanical
shock.
MMAS40G Accelerometers are ideally suited for automotive crash detection
and recording, vibration monitoring, automotive suspension control, appliance
control systems, etc. By Freescale Semiconductor, Inc
