Product details
Overview
ADXL356TEZ-EP-RL from Analog Devices is a hermetically sealed, analog-output, 3-axis MEMS accelerometer engineered for precision inertial sensing in extreme environments. It delivers ±10 g / ±40 g selectable ranges, 80 µg/√Hz noise density, 0.75 mg/°C max 0 g offset drift over −55°C to +125°C, and 150 µA typical current in measurement mode - enabling high-stability tilt sensing and seismic imaging where calibration minimization is critical.
For engineers reviewing the ADXL356TEZ-EP-RL datasheet, ADXL356TEZ-EP-RL pinout, ADXL356TEZ-EP-RL application, or ADXL356TEZ-EP-RL equivalent, key selection considerations include military-grade temperature operation, hermetic LCC packaging, ratiometric analog output scaling, integrated temperature sensor output (963.3 mV at 25°C), and self-test capability via ST1/ST2 pins.
Technical Context
The ADXL356TEZ-EP-RL integrates three orthogonal capacitive MEMS sensing elements with low-noise signal conditioning, fixed 1.5 kHz sinc-filtered analog outputs, and on-chip power management supporting dual supply configurations (VSUPPLY-enabled LDO or external 1.8 V analog/digital rails). Its hermetic ceramic LCC package ensures long-term zero-g stability under thermal cycling and mechanical stress.
Control logic enables range selection (RANGE pin), standby/measurement mode (STBY), and electromechanical self-test activation (ST1/ST2), while the integrated temperature sensor provides a calibrated 3.0 mV/°C output referenced to V1P8ANA/2 - all operating across the full −55°C to +125°C enhanced product temperature range without derating.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Output Full-Scale Range | ±10 g / ±40 g - user-selectable via RANGE pin; determines sensitivity (80 mV/g or 20 mV/g typ) and dynamic range for IMU or structural monitoring |
| Noise Density | 80 µg/√Hz - enables resolution of sub-millig acceleration signals up to 1.5 kHz bandwidth, critical for vibration-based condition monitoring |
| 0 g Offset Drift | ±0.75 mg/°C max - guarantees minimal calibration drift across military temperature range, reducing field recalibration needs in AHRS |
| Supply Current (Meas.) | 150 µA typ at VSUPPLY = 3.3 V - supports low-power battery-operated platforms like portable seismic sensors |
| Operating Temp Range | −55°C to +125°C - qualified per AQEC standard for defense/aerospace deployment without thermal derating |
| Package | 14-terminal LCC, 6.0 mm × 5.6 mm × 2.05 mm - hermetic ceramic construction ensures >20-year stability in harsh environments |
| Temperature Sensor | 963.3 mV @ 25°C, 3.0 mV/°C scale factor - provides on-chip thermal compensation reference traceable to internal analog rail |
Pinout & Package
ADXL356TEZ-EP-RL uses a 14-terminal, 6.0 mm × 5.6 mm × 2.05 mm hermetic ceramic leadless chip carrier (LCC, package option E-14-1), designed for high-reliability mounting on rigid PCBs with thermal vias per JEDEC JESD51-2S2P.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| RANGE | Range selection input | Logic-level control: GND = ±10 g, VDDIO = ±40 g - sets full-scale and sensitivity without reconfiguration overhead |
| ST1 / ST2 | Self-test activation inputs | Electromechanical actuation control: simultaneous assertion triggers known acceleration output shift (±1.25 g on ZOUT) |
| STBY | Mode control input | GND = standby (21 µA), VDDIO = measurement (150 µA) - enables rapid wake-up (<10 ms) for duty-cycled sensing |
| XOUT / YOUT / ZOUT | Analog acceleration outputs | Ratiometric voltage outputs (referred to V1P8ANA/2); dc-coupled, 32 kΩ series resistance - directly interfaceable with 16-bit SAR ADCs |
| TEMP | Integrated temperature sensor output | Calibrated analog voltage (963.3 mV @ 25°C, 3.0 mV/°C) - used for real-time thermal compensation of offset/sensitivity |
| V1P8ANA / V1P8DIG | External analog/digital supply inputs | Accept 1.62–1.98 V when LDO bypassed - decoupling required; enables independent rail control for noise isolation |
| VSUPPLY | Main supply input | 2.25–3.6 V with internal LDO enabled; connect to VSS to disable LDO and use external 1.8 V supplies |
Key Features

Equivalent & Alternatives
The following parts are listed as comparable options for similar precision analog-output 3-axis accelerometer applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| ADXL357BEZ-RL7 | Digital SPI output; same noise (80 µg/√Hz), offset drift (0.75 mg/°C), and temp range; no analog outputs or TEMP pin | Requires external ADC and SPI host; better for digital-centric systems needing daisy-chain capability | Choose ADXL357BEZ-RL7 when digital interface, lower software overhead, or multi-device synchronization are prioritized over analog simplicity. |
| SCA3300-D01 | Higher noise (120 µg/√Hz); narrower temp range (−40°C to +125°C); different package (16-pin LGA); no integrated temp sensor | Suitable for industrial robotics but lacks AQEC qualification and hermetic stability for defense/aerospace | Choose SCA3300-D01 only for cost-sensitive industrial platforms where military-grade reliability and long-term drift are non-critical. |
Compared with ADXL356TEZ-EP-RL, ADXL357BEZ-RL7 offers identical metrology but replaces analog outputs with SPI for embedded processors, while SCA3300-D01 trades hermetic stability and temperature range for lower unit cost - making ADXL356TEZ-EP-RL the sole choice for AQEC-compliant, analog-integrated, ultra-stable inertial sensing.

FAQ
What is the operating temperature range of the ADXL356TEZ-EP-RL?
The ADXL356TEZ-EP-RL operates across −55°C to +125°C, fully qualified per AQEC standards for defense and aerospace applications. This extended range is enabled by hermetic ceramic packaging and controlled manufacturing baseline - no derating is required at temperature extremes, and all specifications including 0 g offset drift (±0.75 mg/°C) and noise density (80 µg/√Hz) are guaranteed across the full range.
Does the ADXL356TEZ-EP-RL support both ±10 g and ±40 g measurement ranges?
Yes, the ADXL356TEZ-EP-RL supports both ±10 g and ±40 g full-scale ranges, selected via the RANGE pin: grounding RANGE selects ±10 g (80 mV/g typical sensitivity), while tying RANGE to VDDIO selects ±40 g (20 mV/g typical sensitivity). This dual-range capability allows one hardware design to serve tilt sensing (±10 g) and shock/vibration analysis (±40 g) without component change.
How does the integrated temperature sensor in the ADXL356TEZ-EP-RL function?
The ADXL356TEZ-EP-RL includes a factory-calibrated analog temperature sensor outputting 963.3 mV at 25°C with a scale factor of 3.0 mV/°C. The TEMP pin output is ratiometric to V1P8ANA/2, enabling direct compensation of offset and sensitivity drift in firmware using linear or polynomial models - critical for maintaining accuracy in uncontrolled thermal environments.
What is the power consumption of the ADXL356TEZ-EP-RL in measurement and standby modes?
In measurement mode with VSUPPLY = 3.3 V and LDO enabled, the ADXL356TEZ-EP-RL draws 150 µA typical; in standby mode under the same conditions, it draws 21 µA typical. When LDO is bypassed and external 1.8 V supplies are used, analog supply current drops to 138 µA and digital supply current to 12 µA in measurement mode - enabling ultra-low-power operation in battery-constrained platforms.
Is the ADXL356TEZ-EP-RL pin-compatible with other ADXL35x-EP variants?
Yes, the ADXL356TEZ-EP-RL shares identical pin configuration, package (E-14-1 LCC), and footprint with ADXL355TEZ-EP-RL and ADXL357BEZ-RL7. However, functional differences exist: ADXL355 is single-axis, ADXL357 provides digital SPI output instead of analog outputs, and ADXL356TEZ-EP-RL retains all three analog outputs plus TEMP - requiring schematic review before substitution.
