Single-axis MEMS accelerometer provides a ratiometric analog output for high-frequency vibration and condition monitoring. The device measures a ±50 g range with 40 mV/g typical sensitivity and 25 µg/√Hz typical noise density from 100 Hz to 10 kHz. It operates from a 3.3 V to 5.25 V single supply and draws 1.0 mA typical quiescent current. Integrated electromechanical self-test, overrange indication, and standby mode support embedded monitoring applications over a −40°C to +125°C operating temperature range.
