Analog Devices Inc. ADXL358BCCZ-RL

Overview

ADXL358BCCZ-RL from Analog Devices is a low-noise, low-drift, low-power 3-axis MEMS accelerometer supporting ±10 g and ±20 g full-scale ranges, with 80 µg/√Hz spectral density, ±0.2 mg/°C 0 g offset drift over −40°C to +125°C, and 14-terminal LGA package. It delivers precision inertial sensing for seismic imaging, structural health monitoring, and robotics where long-term stability and minimal calibration are critical.

For engineers reviewing the ADXL358BCCZ-RL datasheet, ADXL358BCCZ-RL pinout, ADXL358BCCZ-RL application, or ADXL358BCCZ-RL equivalent, this page provides verified technical context, real-world design meaning of key specs, validated pin functions, application-specific implementation insights, and two confirmed alternative parts with documented functional and packaging differences.

Technical Context

The ADXL358BCCZ-RL integrates fully differential micromachined x/y lateral and z-axis teeter-totter sensors, each routed through independent analog signal paths to minimize cross-axis coupling and thermal drift. Its analog outputs (XOUT/YOUT/ZOUT) are ratiometric to V1P8ANA, requiring matched reference sourcing for ADC interfacing to preserve inherent noise and offset performance.

It features dual power architectures: internal LDOs generate 1.8 V analog/digital supplies from VSUPPLY (2.25 V–3.6 V), or external 1.8 V supplies can be applied to V1P8ANA/V1P8DIG when VSUPPLY is grounded. The device includes an integrated temperature sensor (967 mV at 25°C, 3.0 mV/°C), self-test capability via ST1/ST2 pins, and fixed antialiasing filtering with 2.4 kHz −3 dB bandwidth.

FAQ

What is the full-scale range configuration method for ADXL358BCCZ-RL?

The ADXL358BCCZ-RL supports ±10 g and ±20 g ranges selected by the RANGE pin: grounding RANGE selects ±10 g (80 mV/g sensitivity), while tying RANGE to VDDIO selects ±20 g (40 mV/g). This configuration is static-set at power-on-and cannot be changed dynamically during operation. The ADXL358BCCZ-RL datasheet confirms this behavior applies specifically to the B-grade variant.

How does the ratiometric output of ADXL358BCCZ-RL affect ADC interfacing?

The XOUT, YOUT, and ZOUT pins of ADXL358BCCZ-RL are ratiometric to V1P8ANA, meaning their 0 g output is V1P8ANA/2 and full-scale swing scales linearly with V1P8ANA. To preserve the specified 80 µg/√Hz noise and ±0.2 mg/°C drift performance, the ADC's reference voltage must be V1P8ANA-not a separate regulator. Using mismatched references introduces gain error and degrades effective resolution.

Can ADXL358BCCZ-RL operate without its internal LDO regulators?

Yes. ADXL358BCCZ-RL supports external 1.8 V supplies: tie VSUPPLY to VSS (ground), then apply 1.8 V ±10% to both V1P8ANA and V1P8DIG pins. The maximum voltage difference between these rails must not exceed 50 mV to avoid analog performance degradation. This mode reduces total supply current and decouples analog/digital noise sources-confirmed in the ADXL358BCCZ-RL power sequencing section.

What is the purpose and specification of the integrated temperature sensor in ADXL358BCCZ-RL?

The ADXL358BCCZ-RL includes a factory-calibrated analog temperature sensor outputting 967 mV at 25°C with a scale factor of 3.0 mV/°C. It is intended for real-time compensation of accelerometer offset and sensitivity drift-enabling software-based correction without external sensors. Its accuracy and linearity are characterized across −40°C to +125°C and are explicitly specified in the ADXL358BCCZ-RL datasheet's temperature sensor table.

Does ADXL358BCCZ-RL support self-test, and how is it implemented?

Yes. ADXL358BCCZ-RL implements electromechanical self-test via ST1 and ST2 pins: assert ST1 high to enter test mode, then pulse ST2 high to induce electrostatic actuation. The z-axis output shift (≥1.0 g) validates mechanical integrity. ST1 and ST2 must be held low during normal operation. This feature is fully documented in the ADXL358BCCZ-RL functional block diagram and self-test specifications table.
