What this accelerometer does — and where it fits
The ADXL343BCCZ-RL is a 3-axis digital accelerometer from Analog Devices that measures acceleration along X, Y, and Z axes. It outputs data over I²C or SPI, skipping the need for an external ADC. The selectable range spans ±2g, ±4g, ±8g, and ±16g, making it equally usable for tilt sensing in a portable device and shock monitoring in industrial equipment. Bandwidth is adjustable from 0.05 Hz up to 1.6 kHz, so you can trade noise floor against response speed per application. The 14-LGA package (3x5 mm) fits tight PCB layouts, and the -40°C to 85°C operating range covers factory-floor and outdoor-telecom enclosures without a temperature grade penalty.
Selecting the acceleration range — what ±2g vs ±16g means for your BOM
The sensitivity scales inversely with range: at ±2g you get 256 LSB/g resolution, at ±16g it drops to 32 LSB/g. For a handheld inclinometer or gesture interface, the ±2g setting gives finer angular resolution. For a drop-impact recorder or vibration monitor on a motor housing, the ±16g range avoids clipping on high-g events. The same part covers both — no need to qualify two different accelerometer SKUs.
Lifecycle and compliance — no obsolescence risk for new designs
ADI lists the ADXL343BCCZ-RL as Active. ROHS3 compliant per. For a BOM freeze or a new-product introduction, this part carries no near-term supply disruption risk.
Package and mounting — 14-LGA land pattern
The 14-LGA package measures 3x5 mm. Surface-mount only. The supplier device package is 14-LGA (3x5). The Tape & Reel variant (the -RL suffix) feeds directly into a pick-and-place line; no tray-handling step needed.
