Product details
Overview
ADXL356TEZ-EP-RL7 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 measurement 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.
For engineers reviewing the ADXL356TEZ-EP-RL7 datasheet, ADXL356TEZ-EP-RL7 pinout, ADXL356TEZ-EP-RL7 application, or ADXL356TEZ-EP-RL7 equivalent, key selection criteria include military-grade temperature operation, hermetic LCC packaging, ratiometric analog outputs, integrated temperature sensor output, and self-test capability via ST1/ST2 pins.
Technical Context
The ADXL356TEZ-EP-RL7 implements a fully differential capacitive 3-axis sensing element with on-chip signal conditioning, fixed 1.5 kHz sinc low-pass filtering, and independent analog voltage outputs (XOUT/YOUT/ZOUT) referenced to V1P8ANA. Its internal LDO supports dual-supply operation (VSUPPLY = 2.25–3.6 V) or external 1.8 V analog/digital rails when bypassed.
Range selection is hardware-configured via the RANGE pin (ground = ±10 g, VDDIO = ±40 g); standby mode is controlled by STBY; and electromechanical self-test is activated using ST1 and ST2. The integrated temperature sensor provides 3.0 mV/°C scale factor with 963.3 mV output at 25°C.
Key Specifications

|---|---|
| Measurement Ranges | ±10 g and ±40 g - selected via RANGE pin; enables single-device coverage of low- and high-dynamic-range applications |
| Noise Density | 80 µg/√Hz - ensures resolution down to sub-millig-level acceleration in broadband condition monitoring |
| 0 g Offset Drift | ±0.75 mg/°C max (−55°C to +125°C) - minimizes calibration frequency in aerospace IMUs and AHRS |
| Supply Current | 150 µA typical (measurement), 21 µA typical (standby) - supports battery-operated structural health monitoring nodes |
| Operating Temperature | −55°C to +125°C - qualified per AQEC standard for defense/aerospace deployment without derating |
| Package | 14-terminal ceramic LCC (6.0 mm × 5.6 mm × 2.05 mm) - hermetic seal ensures long-term stability in humid or corrosive mil-aero environments |
| Output Type | Analog voltage (XOUT/YOUT/ZOUT) ratiometric to V1P8ANA - simplifies ADC interfacing with shared reference and eliminates ratio-metric error |
Pinout & Package
ADXL356TEZ-EP-RL7 uses a 14-terminal, 6.0 mm × 5.6 mm × 2.05 mm ceramic leadless chip carrier (LCC, package option E-14-1) with hermetic sealing for enhanced reliability in harsh environments.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| RANGE | Range selection input | Ground = ±10 g range; VDDIO = ±40 g range - sets full-scale sensitivity (73.6–86.4 mV/g or 18.4–21.6 mV/g) |
| ST1, ST2 | Self-test control inputs | Activate electrostatic actuation to verify sensor integrity and signal chain without mechanical stimulus |
| STBY | Mode control input | Ground = standby (21 µA), VDDIO = measurement (150 µA) - enables rapid wake-up (<10 ms turn-on time) |
| XOUT, YOUT, ZOUT | Analog acceleration outputs | Voltage outputs proportional to acceleration on respective axes; ratiometric to V1P8ANA reference |
| TEMP | Integrated temperature sensor output | 963.3 mV at 25°C, 3.0 mV/°C scale factor - enables on-board thermal compensation without external sensor |
| V1P8ANA, V1P8DIG | Analog/digital supply pins | Support external 1.8 V ±10% supplies when LDO is bypassed (VSUPPLY = VSS); require local decoupling |
| VSUPPLY | Main supply input | 2.25–3.6 V input enabling internal LDOs to generate regulated 1.8 V analog/digital rails |

Equivalent & Alternatives
The following parts are listed as comparable options for similar high-stability analog-output accelerometer applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| ADXL355BEZ-RL7 | Digital (I²C/SPI) output; same ±10 g/±40 g ranges, 80 µg/√Hz noise, but no hermetic package or military temp rating | Lacks AQEC qualification and −55°C to +125°C operation; suited for commercial industrial use only | Select ADXL355BEZ-RL7 only if digital interface and lower cost outweigh need for hermetic reliability and extended temperature range |
| IAQ200-100 | Capacitive analog output; ±100 g range; higher noise (200 µg/√Hz); non-hermetic metal-can package; −40°C to +85°C | Designed for automotive crash sensing, not precision inertial measurement; lacks integrated temperature sensor and self-test | Choose IAQ200-100 only for high-g shock detection where resolution and long-term stability are secondary to cost and ruggedness |
Compared with ADXL355BEZ-RL7 and IAQ200-100, the ADXL356TEZ-EP-RL7 uniquely combines hermetic stability, military temperature range, integrated temperature sensing, and ultralow noise - making it the sole option for mission-critical defense IMUs and seismic instrumentation requiring <0.1 mg/°C drift control.

FAQ
What is the operating temperature range of the ADXL356TEZ-EP-RL7?
The ADXL356TEZ-EP-RL7 operates across −55°C to +125°C, qualified per AQEC standards for defense and aerospace applications. This extended range is enabled by hermetic ceramic packaging and controlled manufacturing at a single fabrication and test site, ensuring parametric stability without derating under thermal stress.
Does the ADXL356TEZ-EP-RL7 support both ±10 g and ±40 g measurement ranges?
Yes, the ADXL356TEZ-EP-RL7 supports both ±10 g and ±40 g full-scale ranges. Range selection is performed 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-based configuration requires no firmware intervention.
How does the integrated temperature sensor in the ADXL356TEZ-EP-RL7 function?
The ADXL356TEZ-EP-RL7 integrates a calibrated temperature sensor with 963.3 mV output at 25°C and 3.0 mV/°C scale factor, accessible via the TEMP pin. This allows real-time thermal compensation of offset and sensitivity drift in applications like IMUs and AHRS without requiring an external sensor or additional PCB area.
What power supply configurations does the ADXL356TEZ-EP-RL7 support?
The ADXL356TEZ-EP-RL7 supports two supply modes: VSUPPLY = 2.25–3.6 V enables internal LDOs to generate 1.8 V analog (V1P8ANA) and digital (V1P8DIG) rails; or VSUPPLY = VSS disables the LDOs, allowing external 1.8 V ±10% supplies to be applied directly to V1P8ANA and V1P8DIG pins with local decoupling.
Is the ADXL356TEZ-EP-RL7 pin-compatible with other devices in the ADXL35x family?
No, the ADXL356TEZ-EP-RL7 is not pin-compatible with ADXL354, ADXL355, or ADXL357. Its 14-terminal LCC pinout includes dedicated RANGE, ST1, ST2, and TEMP pins not present in digital-output variants. Hardware design must follow the specific pin configuration shown in Figure 2 of the ADXL356-EP datasheet.
