Vibration sensing up to bearing fault frequencies
The ADXL1001BCPZ-RL7 is a single-axis (X) analog-output MEMS accelerometer rated for ±100g full-scale with a 21 kHz bandwidth. That bandwidth covers the vibration signature of rotating machinery up to bearing defect frequencies and gear mesh harmonics — the range where early-stage faults show up before they propagate to structural resonance. The 20 mV/g sensitivity means a 10g peak vibration produces a 200 mV analog output, which a typical 3.3V or 5V ADC can resolve with a 12-bit converter without a pre-amp stage. Supply voltage flexibility from 3.3V to 5.25V lets it drop into existing analog front-end rails without a dedicated regulator. The analog voltage output (not SPI/I2C) means the signal chain needs an external ADC — a consideration for systems that currently use digital-output accelerometers and would need a layout change to add the converter.

Surface-mount assembly with the 5x5 mm footprint fits standard pick-and-place.
Sourcing and compliance
The ADXL1001BCPZ-RL7 is the correct choice when the measurement requires the full ±100g dynamic range and 21 kHz bandwidth on a single axis.
