Product details
Overview
ADXL356TEZ-EP 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 operates at 150 µA typical in measurement mode. It serves as the core sensor in aerospace-grade IMUs and seismic monitoring systems requiring long-term stability.
For engineers reviewing the ADXL356TEZ-EP datasheet, ADXL356TEZ-EP pinout, ADXL356TEZ-EP application, or ADXL356TEZ-EP equivalent, key selection criteria include military-temperature operation, hermetic LCC packaging, ratiometric analog outputs, integrated temperature sensing, and self-test capability across all axes.
Technical Context
The ADXL356TEZ-EP integrates a triaxial capacitive MEMS sensor with low-noise signal conditioning, fixed 1.5 kHz sinc-filtered analog outputs, and dual LDO regulators supporting internal or external 1.8 V analog/digital supplies. Its control logic uses discrete digital pins (RANGE, STBY, ST1, ST2) - no serial interface - enabling deterministic timing and radiation-tolerant configuration.
It features a dedicated temperature sensor (963.3 mV at 25°C, 3.0 mV/°C scale factor), vibration rectification error <0.1 g under 7.5 grms, and resonant frequency of 5.5 kHz - all specified and tested across the full −55°C to +125°C military temperature range per AQEC standards.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Output Range | ±10 g or ±40 g - selected via RANGE pin; enables single-device coverage of high-sensitivity tilt and high-g shock detection. |
| Noise Density | 80 µg/√Hz - supports sub-micro-g resolution in wireless condition monitoring up to 1 kHz bandwidth. |
| 0 g Offset Drift | ±0.75 mg/°C - ensures <1.5 mg total drift over full military temperature range, minimizing calibration burden. |
| Supply Current | 150 µA (measurement), 21 µA (standby) - enables multi-year battery life in remote structural health sensors. |
| Operating Temp | −55°C to +125°C - qualified per AQEC for defense/aerospace deployment without derating. |
| Package | 14-terminal ceramic LCC (6.0 × 5.6 × 2.05 mm) - hermetic seal guarantees long-term parameter stability in humid or corrosive atmospheres. |
| Self-Test Output | Z-axis shift of ±1.25 g - provides on-demand electromechanical verification without external stimulus. |
Pinout & Package
ADXL356TEZ-EP uses a 14-terminal, 6.0 mm × 5.6 mm × 2.05 mm hermetic ceramic leadless chip carrier (LCC, package option E-14-1), qualified for enhanced product reliability in defense and aerospace applications.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| RANGE | Range selection input | Ground = ±10 g; VDDIO = ±40 g - hardware-configured, no firmware dependency. |
| ST1, ST2 | Self-test activation inputs | Enable electrostatic actuation of proof mass; allows in-system functional verification before mission-critical use. |
| STBY | Mode control input | Ground = standby (21 µA); VDDIO = active measurement (150 µA) - ultra-low-power wake-on-event capability. |
| XOUT, YOUT, ZOUT | Analog voltage outputs | Ratiometric to V1P8ANA (73.6–86.4 mV/g @ ±10 g); dc-coupled, 32 kΩ output impedance - direct interface to precision ADCs. |
| TEMP | Integrated temperature sensor output | 963.3 mV at 25°C, 3.0 mV/°C - enables real-time thermal compensation of offset and sensitivity without external sensor. |
| V1P8ANA, V1P8DIG | Separate analog/digital supply pins | Support LDO bypass for externally regulated 1.8 V supplies - eliminates switching noise coupling into analog path. |
| VSUPPLY | Main supply input | 2.25–3.6 V; enables internal LDOs or disables them when tied to VSS - flexible power architecture for mixed-voltage systems. |
Key Features
| Feature | Design Value |
|---|---|
| Hermetic ceramic packaging | Eliminates parameter drift due to moisture ingress or outgassing - critical for >10-year field deployments in IMUs. |
| Ultralow vibration rectification error | <0.1 g under 7.5 grms vibration - preserves accuracy in high-vibration platforms like helicopters and turbine engines. |
| User-adjustable analog bandwidth | Fixed 1.5 kHz sinc filter - no external components needed; rejects aliasing while maintaining phase linearity. |
| Controlled manufacturing baseline | Single fab and test site with change notification - ensures consistent parametric performance across production lots and decades. |
| Integrated temperature sensor | Calibrated 3.0 mV/°C output - enables closed-loop thermal compensation algorithms without adding BOM cost or board area. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar 3-axis analog MEMS accelerometer applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| ADXL354BEZ-EP | Single ±2 g range; lower noise (25 µg/√Hz); no RANGE pin; same package and temp range. | Optimized for ultra-high-resolution tilt and low-g vibration - not suitable for ±10/±40 g dynamic range needs. | Select when resolution at sub-100 µg level is prioritized over range flexibility. |
| ADXL355BEZ-EP | Digital I²C/SPI output; ±2 g / ±4 g / ±8 g ranges; 25 µg/√Hz noise; same hermetic LCC and temp range. | Requires microcontroller interface and digital filtering; adds firmware complexity but enables on-chip digital features. | Select when system already uses digital sensors and requires synchronized multi-axis sampling or embedded self-test reporting. |
Compared with ADXL356TEZ-EP, ADXL354BEZ-EP trades range programmability for lower noise in narrow-range applications, while ADXL355BEZ-EP replaces analog simplicity with digital configurability - both retain AQEC qualification but differ fundamentally in output architecture and range coverage.

FAQ
What is the operating temperature range of the ADXL356TEZ-EP?
The ADXL356TEZ-EP is rated for continuous operation from −55°C to +125°C and is qualified per AQEC standards for defense and aerospace applications. This full military temperature range is validated across all electrical parameters including offset drift, sensitivity, noise, and self-test functionality - no derating required.
Does the ADXL356TEZ-EP support both ±10 g and ±40 g measurement ranges?
Yes, the ADXL356TEZ-EP supports both ranges via the RANGE pin: grounding it selects ±10 g (73.6–86.4 mV/g sensitivity), while tying it to VDDIO selects ±40 g (18.4–21.6 mV/g). This hardware-selectable dual-range capability is confirmed in the ordering guide and electrical specifications table for ADXL356TEZ-EP.
How does the hermetic package of the ADXL356TEZ-EP improve long-term stability?
The ADXL356TEZ-EP uses a 14-terminal ceramic LCC with hermetic seal to prevent moisture ingress and internal outgassing - directly enabling its ≤0.75 mg/°C 0 g offset drift and stable noise performance over 10+ years. This is documented in the Enhanced Product Features section and verified through accelerated life testing per MIL-STD-883.
Can the ADXL356TEZ-EP operate with externally supplied 1.8 V analog and digital rails?
Yes, the ADXL356TEZ-EP supports LDO bypass: tie VSUPPLY to VSS and supply regulated 1.8 V ±10% to V1P8ANA and V1P8DIG. This configuration reduces power supply noise coupling into analog outputs and is explicitly defined in the Pin Configuration table and Power Supply specifications.
What is the purpose of the ST1 and ST2 pins on the ADXL356TEZ-EP?
The ST1 and ST2 pins on the ADXL356TEZ-EP enable electromechanical self-test: ST1 activates the test circuitry and ST2 triggers proof-mass actuation, producing a calibrated ±1.25 g output shift on ZOUT. This hardware-based test requires no host processor and is fully specified in the Functional Block Diagram and Pin Function Descriptions.
