ADXL345BCCZ 3-axis digital MEMS accelerometer
ADXL345BCCZ is a widely adopted ultra-low-power 3-axis digital MEMS accelerometer designed and manufactured by Analog Devices, packaged in a miniature 14-lead 5×3×1 mm LGA plastic housing with tape-and-reel shipment, MSL 3 moisture sensitivity rating, RoHS-compliant construction and a wide industrial operating temperature window spanning -40°C to +85°C, capable of enduring mechanical shock up to 10,000 g for rugged consumer and light industrial hardware deployment.
It supports four user-selectable acceleration measurement ranges of ±2 g, ±4 g, ±8 g and ±16 g, delivering flexible resolution modes including fixed 10-bit output and full-scale 13-bit high-resolution sampling with a consistent 3.9 mg/LSB sensitivity to capture tiny tilt variations below 1 degree, while power consumption dynamically scales with bandwidth, drawing only 0.1 µA in standby mode and 23 µA typical current under 2.5 V supply during active measurement to extend battery life for portable devices. With a supply voltage range of 1.8 V to 3.6 V, built-in self-test function for production validation and robust static tilt plus dynamic shock measurement capability, ADXL345BCCZ serves as a mainstream solution for smartphone gesture control, gaming peripherals, hard disk drive anti-shock protection, wearable fitness trackers, digital camera orientation detection, handheld navigation tools and low-cost industrial tilt sensing equipment that demands compact size, low power and integrated motion event logic.
