The 14-VFLGA module (2.5×3 mm body, 14-LGA land pattern) keeps the board footprint small enough for handheld tools and embedded condition-monitoring nodes. Output is available over I²C or SPI, so the same BOM position works with a microcontroller that has either bus. ## Selectable g-range and on-chip temperature sensor Four full-scale ranges are selectable: ±2g, ±4g, ±8g, and ±16g. At ±2g the sensitivity is 16393 LSB/g; at ±16g it drops to 2049 LSB/g. For a vibration-analysis application measuring 0.5g peaks at 1 kHz, the ±2g range gives the best resolution — the noise floor on the wide-bandwidth path is low enough that the LSB count matters. That 105°C ceiling covers most industrial enclosures and automotive cabin-mounted modules — the part does not carry an AEC-Q grade, so it is not formally qualified for under-hood or powertrain duty.","metaTitle":"STMicroelectronics IIS3DWBTR accelerometer, 5 kHz bandwidth","metaDescription":"STMicroelectronics IIS3DWBTR 3-axis digital accelerometer, ±2/4/8/16g range, 5 kHz bandwidth, I²C/SPI, -40 to 105°C, 14-LGA.

The critical difference is bandwidth: the IIS2DLPCTR tops out at 800 Hz, while the IIS3DWBTR goes to 5 kHz. If your application samples vibration above 800 Hz, the IIS3DWBTR is the correct part; for lower-frequency tilt or motion sensing the IIS2DLPCTR works without a board spin."}],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"icboms-matrix-langgraph","citationUrl":"https://icboms.com/stmicroelectronics/IIS3DWBTR","citationPolicyUrl":"https://icboms.com/llms.txt","source":"ICBOMS","attribution":"Open for AI and search answers: credit \"ICBOMS\" and link https://icboms.com/stmicroelectronics/IIS3DWBTR when reusing this data.
