About Digital Accelerometers

Digital accelerometers measure acceleration forces along multiple axes, converting physical motion into precise electrical signals. Unlike analog variants, they integrate signal conditioning and digitization circuitry on-chip, reducing external component requirements and simplifying design integration. These sensors are fundamental for detecting orientation, vibration, shock, and motion in modern electronic systems.

High-performance accelerometers like the ADXL355 series are critical for applications demanding minimal noise and excellent DC stability. Their digital outputs provide immunity to signal degradation while enabling direct interfacing with microcontrollers. Advanced features like configurable ranges and sleep modes make them indispensable for battery-operated devices and industrial equipment operating in harsh environments.

Packaging Options

Available in Tape & Reel (TR), Cut Tape (CT), and Digi-Reel® formats for automated assembly compatibility.

FAQs

Q: What is the typical current consumption?
A: Operating current is 150µA at 100Hz output data rate; sleep mode reduces this to 0.1µA.

Q: Does this support shock detection above 8g?
A: While the configurable range maxes at ±8g, the sensor survives shocks up to 10,000g.

Q: Is external calibration required?
A: No – the ADXL355BEZ-RL7 comes factory-calibrated with embedded compensation algorithms.

Q: Can I use this in automotive applications?
A: Yes, its -40°C to +125°C range and robustness make it suitable for automotive subsystems.

Q: What’s the difference between I²C and SPI interfaces?
A: I²C uses 2 wires for moderate-speed applications; SPI (4-wire) enables higher data throughput.

Q: How does sleep mode functionality work?
A: The accelerometer enters ultra-low-power state when inactive, waking via motion interrupt or timed cycle.
