Product details
Overview
ADXL358BCCZ-RL7 from Analog Devices is a low-noise, low-drift, 3-axis MEMS accelerometer with ±10 g / ±20 g selectable full-scale ranges, 80 µg/√Hz noise spectral density, ±0.2 mg/°C 0 g offset drift over −40°C to +125°C, and 2.4 kHz −3 dB bandwidth. It delivers precision inertial sensing for seismic imaging, structural health monitoring, and high-stability IMUs.
For engineers reviewing the ADXL358BCCZ-RL7 datasheet, ADXL358BCCZ-RL7 pinout, ADXL358BCCZ-RL7 application, or ADXL358BCCZ-RL7 equivalent, this page provides verified technical context, real-world design meaning of key specs, validated alternative options, and supply-ready availability details - all grounded in the official Rev. 0 datasheet and Analog Devices' ordering guide.
Technical Context
The ADXL358BCCZ-RL7 integrates fully differential micromachined x/y lateral and z-axis teeter-totter sensors, each routed through independent low-drift analog signal paths. Its outputs (XOUT/YOUT/ZOUT) are ratiometric to V1P8ANA, requiring matched reference use with ADCs like the AD7682 to preserve inherent offset and noise performance.
It features dual power architectures: internal LDOs generate 1.8 V analog/digital supplies from VSUPPLY (2.25–3.6 V), or external 1.8 V supplies can bypass regulators via VSUPPLY = VSS. The analog outputs include a fixed 32 kΩ series resistor enabling user-defined RC filtering, while internal antialiasing yields a 1.5 kHz filter corner and overall 2.4 kHz −3 dB system bandwidth.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Full-Scale Range | ±10 g or ±20 g (pin-selectable via RANGE pin); enables trade-off between resolution and dynamic range in vibration or tilt applications. |
| Noise Spectral Density | 80 µg/√Hz (±10 g range); supports detection of sub-mg acceleration signals in condition monitoring up to ~2 kHz. |
| 0 g Offset Drift | ±0.2 mg/°C (−40°C to +125°C); minimizes calibration frequency in automotive or industrial environments with wide thermal cycling. |
| Bandwidth (−3 dB) | 2.4 kHz (overall transfer function); captures mechanical resonance signatures and broadband vibration without aliasing when sampled ≥4.8 kSPS. |
| Supply Current | 150 µA in measurement mode (VSUPPLY LDO enabled); enables multi-year battery life in wireless sensor nodes. |
| Operating Temperature | −40°C to +125°C; qualified for under-hood automotive, downhole oil & gas, and industrial control cabinet deployment. |
| Package | 14-terminal, 4 mm × 4 mm × 1.04 mm LGA (CC-14-2); surface-mount compatible with standard reflow profiles and high-density PCB layouts. |
Pinout & Package
ADXL358BCCZ-RL7 uses a 14-terminal Land Grid Array (LGA) package (CC-14-2), 4 mm × 4 mm × 1.04 mm, RoHS-compliant, with exposed paddle for thermal management and no leads - requires controlled solder paste volume and reflow profile per JEDEC JESD-51.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| RANGE | Range selection input | Ground = ±10 g; VDDIO = ±20 g; sets full-scale gain and noise floor for optimal SNR in target application. |
| ST1, ST2 | Self-test control inputs | ST1 high enables test mode; ST2 high applies electrostatic actuation - validates mechanical integrity and signal chain end-to-end. |
| TEMP | Integrated temperature sensor output | 967 mV at 25°C, 3.0 mV/°C scale factor; enables on-chip thermal compensation without external sensor. |
| V1P8ANA | Analog supply & voltage reference | 1.8 V nominal (±10%); ratiometric reference for XOUT/YOUT/ZOUT - must be used as ADC reference to maintain specified offset/noise performance. |
| XOUT, YOUT, ZOUT | Analog acceleration outputs | DC-coupled, ratiometric to V1P8ANA; include 32 kΩ series resistance - external capacitor sets final low-pass cutoff before ADC. |
| VSUPPLY | Main supply input | 2.25–3.6 V; powers internal LDOs for V1P8ANA/V1P8DIG; tie to VSS to disable LDOs and use external 1.8 V supplies. |
Key Features
| Feature | Design Value |
|---|---|
| Ultralow noise spectral density | 80 µg/√Hz enables resolution of <1 mg RMS vibration in 10 Hz bandwidth - critical for early-stage bearing fault detection. |
| Low 0 g offset drift | ±0.2 mg/°C over full temperature range reduces need for multi-point temperature calibration in AHRS and platform stabilization. |
| Integrated temperature sensor | Monolithic 3.0 mV/°C sensor eliminates external component count and thermal mismatch errors in drift-compensated algorithms. |
| User-adjustable analog bandwidth | RC filter formed by 32 kΩ output resistance + external capacitor allows precise anti-aliasing tuning without changing firmware or sampling rate. |
| Overrange protection | Auto-disable of sensor clocks beyond ±40 g (±10 g range) prevents proof mass stiction and preserves long-term bias stability after shock events. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar 3-axis analog-output MEMS accelerometer applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| ADXL354BCCZ-RL7 | Lower noise (25 µg/√Hz), single ±2 g range only; no temperature sensor; 1.5 kHz bandwidth; same LGA package. | Better suited for ultra-low-noise, narrow-dynamic-range applications (e.g., gravimetric survey), but lacks range flexibility and thermal compensation. | Select ADXL354BCCZ-RL7 only if ±2 g range suffices and sub-30 µg/√Hz noise is mandatory - not a drop-in replacement for ADXL358BCCZ-RL7's dual-range or temperature-aware use cases. |
| ICM-20689 | Digital (I²C/SPI) output; integrated 16-bit ADC; higher current (750 µA active); 3.2 kHz bandwidth; different 3×3 mm QFN package. | Targets embedded systems with microcontroller ADC limitations or need for on-chip digital processing; lacks analog ratiometric precision and ultra-low drift. | Choose ICM-20689 when digital interface, lower BOM count, or fused 6-DoF (with gyroscope) is prioritized over analog signal integrity and long-term bias stability. |
Compared with ADXL358BCCZ-RL7, ADXL354BCCZ-RL7 trades range flexibility and thermal sensing for lower noise in fixed-range scenarios, while ICM-20689 replaces analog precision with digital convenience and integrated processing - neither matches ADXL358BCCZ-RL7's combination of ultralow drift, dual-range analog output, and monolithic temperature compensation.

FAQ
What is the full-scale range configuration method for ADXL358BCCZ-RL7?
The ADXL358BCCZ-RL7 supports ±10 g and ±20 g full-scale ranges selected by the RANGE pin: connect RANGE to ground for ±10 g, or to VDDIO for ±20 g. This pin is sampled at power-up and remains latched; no runtime reconfiguration is supported. The ADXL358BCCZ-RL7 datasheet confirms this behavior in Table 4 and the General Description section.
Does ADXL358BCCZ-RL7 include an integrated temperature sensor, and how is it used?
Yes, ADXL358BCCZ-RL7 integrates a monolithic temperature sensor with 967 mV output at 25°C and 3.0 mV/°C scale factor (Table 1, Rev. 0 datasheet). It is accessed via the TEMP pin and used for on-the-fly thermal compensation of offset and sensitivity - eliminating need for external sensors and reducing thermal path mismatch errors in precision applications.
What is the recommended power architecture for ADXL358BCCZ-RL7 in battery-powered applications?
For battery-powered applications, ADXL358BCCZ-RL7 should operate with VSUPPLY supplied from 2.25–3.6 V to enable internal LDOs, delivering 150 µA in measurement mode and 21 µA in standby mode (Table 1). External 1.8 V supplies are discouraged unless system-level noise isolation justifies the added complexity - the internal LDOs provide optimal analog/digital supply separation per the Applications Information section.
How does the ratiometric output of ADXL358BCCZ-RL7 affect ADC interfacing?
The XOUT, YOUT, and ZOUT pins of ADXL358BCCZ-RL7 are ratiometric to V1P8ANA, meaning their 0 g output is nominally V1P8ANA/2 and sensitivity scales linearly with V1P8ANA. To preserve specified noise and offset performance, V1P8ANA must serve as the reference voltage for any external ADC - as confirmed in the Applications Information and Theory of Operation sections of the datasheet.
What is the purpose and activation method of the self-test function in ADXL358BCCZ-RL7?
The ADXL358BCCZ-RL7 self-test verifies mechanical and electronic functionality by electrostatically actuating the sensor proof mass. It is activated by driving ST1 high to enter test mode, then ST2 high to trigger actuation. The resulting output delta (e.g., 1.0–2.20 g on Z-axis) is measured - detailed in Table 1 and the Self Test section. Both pins must be returned low to resume normal operation.
