Product Overview
The ADXL346ACCZ-RL7 is a small, thin, ultra-low power, 3-axis accelerometer with high resolution (13-bit) measurement up to ±16g, manufactured by Analog Devices Inc. Digital output data is formatted as 16-bit twos complement and is accessible through either an SPI (3- or 4-wire) or I2C digital interface. Well-suited for mobile device applications, it measures the static acceleration of gravity in tilt-sensing applications, as well as dynamic acceleration resulting from motion or shock. Its high resolution (4 mg/LSB) enables measurement of inclination changes less than 1.0°. Several special sensing functions are provided, including compliance with orientation detection criteria, tap/double tap sensing, and free-fall detection, making it an exceptional option for smart interfaces and rugged power management layouts.
Core Advantages
Ultra-Low Power Optimization
Operates at micro-level current parameters, drawing as low as 23 µA in full measurement mode and 0.1 µA in standby mode. This exceptional energy efficiency profile maximizes battery longevity in portable device systems.
High-Resolution Measurement Capabilities
Featuring a true 13-bit output layout option across the full ±16g dynamic range, it maintains a stable resolution of 4 mg/LSB. This allows precision tilt and structural stability evaluations inside high-accuracy tracking architectures.
Flexible Embedded System Interfaces
Equipped with built-in SPI and I2C digital connectivity channels, the accelerometer maps cleanly onto standard microcontrollers or application processors. Its onboard 32-level FIFO memory buffer further offloads computational overhead from the host system CPU.
Advanced Motion and Orientation Detection
Integrated hardware intelligence autonomously evaluates tap, double-tap, activity, inactivity, free-fall events, and 3D orientation configurations, executing fast system wakeups or shutdown interrupts without software delay tracks.

Frequently Asked Questions
Q1: Is your stock inventory of the ADXL346ACCZ-RL7 original and factory-new?
A: Yes, we guarantee that all ADXL346ACCZ-RL7 accelerometers are 100% authentic, brand-new components from original factory production lines, carefully preserved in anti-static tape and reel packaging.
Q2: What is the benefit of the integrated FIFO buffer module inside this accelerometer?
A: The onboard 32-level FIFO (first-in, first-out) memory buffer collects acceleration data internally. This allows the host microcontroller to enter a low-power sleep state and only wake up to read bulk data, drastically minimizing overall system power load.
Q3: What does the suffix “-RL7” indicate in the orderable part number?
A: The “-RL7” suffix indicates that the product is packaged and shipped on a 7-inch tape and reel format, which is standard for high-speed automated SMD pickup and placement assembly equipment lines.
Q4: How can our engineering desk request specific register configuration profiles and matching PCB layout guidelines?
A: Please complete our Quick Inquiry web form on this page with details about your processing parameters. Our application support desk will process your inquiry and dispatch the available technical documentation package within 24 hours.
