Analog Devices Inc. ADXL358CCCZ-RL

Overview

ADXL358CCCZ-RL from Analog Devices is a low-noise, low-drift, 3-axis MEMS accelerometer supporting ±10 g and ±40 g full-scale ranges, with 80 µg/√Hz noise spectral density, ±0.2 mg/°C 0 g offset drift over −40°C to +125°C, and 150 µA measurement current. It delivers precision inertial sensing for seismic imaging, structural health monitoring, and robotics.

For engineers reviewing the ADXL358CCCZ-RL datasheet, ADXL358CCCZ-RL pinout, ADXL358CCCZ-RL application, or ADXL358CCCZ-RL equivalent, key selection criteria include its ratiometric analog outputs referenced to V1P8ANA, integrated temperature sensor (3.0 mV/°C), user-adjustable bandwidth via external RC filtering, and LGA-14 package compatibility with high-reliability industrial and aerospace signal chains.

Technical Context

The ADXL358CCCZ-RL implements fully differential micromachined sensing elements-lateral x/y-axis and vertical teeter-totter z-axis-with independent signal paths minimizing cross-axis coupling and thermal drift. Its analog outputs (XOUT/YOUT/ZOUT) are ratiometric to V1P8ANA, requiring matched reference for ADC digitization to preserve specified noise and offset performance.

It features dual power architectures: internal LDOs enabled by VSUPPLY (2.25–3.6 V) generating regulated 1.8 V supplies, or external 1.8 V sourcing to V1P8ANA/V1P8DIG when VSUPPLY = VSS. The device includes self-test actuation via ST1/ST2 pins, overrange protection triggering at ±40 g (±10 g range) or ±80 g (±40 g range), and fixed 1.5 kHz antialiasing filter plus mechanical resonance shaping overall bandwidth to 2.4 kHz (−3 dB).

FAQ

What is the full-scale range configuration for ADXL358CCCZ-RL?

The ADXL358CCCZ-RL supports two full-scale ranges: ±10 g and ±40 g. Range selection is controlled by the RANGE pin-grounded for ±10 g, driven to VDDIO for ±40 g. This pin-selectable architecture allows one hardware design to serve both high-resolution tilt sensing and high-g shock detection without changing the ADXL358CCCZ-RL footprint or bill of materials.

How does the ratiometric output of ADXL358CCCZ-RL affect ADC interfacing?

The XOUT, YOUT, and ZOUT analog outputs of ADXL358CCCZ-RL are ratiometric to V1P8ANA, meaning their scale factor (e.g., 80 mV/g at ±10 g) changes proportionally with V1P8ANA voltage. To preserve specified accuracy, ADXL358CCCZ-RL must be digitized using a ratiometric ADC-such as the AD7682-with V1P8ANA as the reference voltage, ensuring supply-induced gain errors cancel out.

What is the role of the integrated temperature sensor in ADXL358CCCZ-RL?

The ADXL358CCCZ-RL includes an on-die temperature sensor with 3.0 mV/°C scale factor and 967 mV output at 25°C. This sensor provides real-time die temperature data to enable software-based compensation of 0 g offset drift (±0.2 mg/°C) and sensitivity variation (±0.02 %/°C), improving long-term accuracy in uncontrolled thermal environments.

Can ADXL358CCCZ-RL operate with external 1.8 V supplies instead of internal LDOs?

Yes-ADXL358CCCZ-RL supports external 1.8 V supplies for V1P8ANA and V1P8DIG by tying VSUPPLY to VSS. In this mode, both supplies must be within 1.62 V to 1.98 V and match within ±50 mV. External sourcing bypasses internal LDO noise, yielding optimal analog performance in ultra-low-noise measurement systems where supply regulation is already handled externally.

What self-test functionality does ADXL358CCCZ-RL provide, and how is it activated?

ADXL358CCCZ-RL provides electromechanical self-test via ST1 and ST2 pins. Driving ST1 high enables test mode; pulsing ST2 high applies electrostatic force to the proof mass, producing calibrated output shifts (e.g., 1.0–2.20 g on Z-axis). This verifies mechanical integrity and analog signal chain functionality without external shakers or fixtures-critical for field-deployed ADXL358CCCZ-RL units requiring periodic validation.
