Supply voltage spans 2.5V to 3.3V, so the same part works on a 2.8V or 3.0V rail without a separate regulator — one BOM line covers multiple board variants.
4-VLGA package and board layout
Housed in a 4-VLGA package measuring 2.50mm x 2.00mm with a seated height of 0.89mm — the small footprint leaves room for decoupling caps close to the supply pin, which keeps the power rail clean for the MEMS core. Surface-mount assembly; the 4-pin VLGA layout requires a standard reflow profile for lead-free solder. No exposed pad means the thermal path is through the solder joints — keep the trace width adequate for the 7.5 mA draw.
