Overview
The MMA2712WCR2 is a high‑g digital MEMS accelerometer designed for robust motion and impact sensing applications. It is widely used in industrial machinery monitoring, automotive crash detection, and vibration/impact logging systems, where high acceleration range, digital interface, and reliable performance across temperature extremes are required. The device originates from NXP’s MMA27xxW family of DSI3 compatible inertial sensors.
Core Parameters
| Parameter | Specification |
|---|---|
| Sensor Type | Digital MEMS Accelerometer |

For applications requiring an even higher acceleration range, the ADXL377BCPZ‑RL7 from Analog Devices serves as a complementary solution. With a ±200 g measurement range and robust analog output, it is ideal for extreme shock and impact monitoring, while MMA2712WCR2 remains suitable for precise ±125 g digital acceleration sensing. Designers can leverage both sensors in parallel or choose based on their system’s required g-range and interface preferences, providing flexibility for automotive, industrial, and high‑impact applications.
Performance Comparison
| Feature | MMA2712WCR2 | Typical Analog Accelerometer |
|---|---|---|
| Output Type | Digital (PCM/SPI) | Analog voltage |
| Acceleration Range | ±125 g | ±2 g to ±16 g |
| Noise Filtering | Selectable digital filter | Passive analog filtering |
| Voltage Range | 4 V–20 V | 3 V–5 V |
| Industrial Range | Yes | Limited |
Compared with typical analog accelerometers, MMA2712WCR2 provides a higher acceleration range, robust digital interface, and configurable filtering, enabling better performance in high‑impact and high‑noise environments.
