Active production, single-axis digital accelerometer for ±60g impact and vibration sensing
The MMA5148KWR2: The sensitivity is fixed at 8 LSB/g, so a 60g event produces a 480-count digital word — the SPI bus carries the result without an external ADC. Supply range spans 4.2 V to 17 V, covering both regulated 5 V rails and unregulated battery voltages in automotive or industrial environments.
Temperature grade and package for harsh-environment deployment
Surface-mount assembly with the exposed pad requires a solder-paste stencil aperture that covers at least 50% of the pad area — the datasheet landing pattern on page 14 shows the recommended copper and solder-mask geometry.
SPI interface and digital filtering for system integration
The SPI output eliminates analog routing and external filtering — the selectable low-pass filter on-chip lets the firmware choose the corner frequency to match the mechanical resonance of the target structure.
