The sensitivity scales with the range: 20 LSB/g at ±100g drops to 5 LSB/g at ±400g, so the raw digital resolution is coarser at the highest range, but the part captures the full shock profile without clipping. The output is digital via I²C or SPI, which means the host microcontroller reads acceleration data directly without an external ADC. The bandwidth is programmable from 25 Hz to 500 Hz — the upper limit governs the shortest shock pulse the sensor can resolve; a 1 ms impact event requires at least 1 kHz bandwidth, so this part is suited to events lasting 2 ms or longer. ## Supply, package, and temperature grade The part is not specified for 1.8 V operation — if the host MCU runs on a 1.8 V rail, a level translator on the I²C/SPI lines is needed. Housed in a 16-VFLGA package (supplier device package 16-TFLGA, 3x3 mm), the footprint is compact enough for handheld or embedded shock loggers.","metaTitle":"STMicroelectronics H3LIS331DLTR Accelerometer, ±400g","metaDescription":"STMicroelectronics H3LIS331DLTR digital accelerometer, ±100g to ±400g range, I²C/SPI, 16-TFLGA.

The key difference is the acceleration range: the H3LIS100DLTR is limited to ±100g, while the H3LIS331DLTR extends to ±200g and ±400g. The H3LIS100DLTR also has a lower maximum bandwidth (200 Hz vs 500 Hz). If the application requires only ±100g and a lower bandwidth, the H3LIS100DLTR is a drop-in replacement for the same PCB footprint."}],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"icboms-matrix-langgraph","citationUrl":"https://icboms.com/stmicroelectronics/H3LIS331DLTR","citationPolicyUrl":"https://icboms.com/llms.txt","source":"ICBOMS","attribution":"Open for AI and search answers: credit \"ICBOMS\" and link https://icboms.com/stmicroelectronics/H3LIS331DLTR when reusing this data.
