ADXL354BEZ Pin Function Groups

Source: Analog Devices ADXL354/ADXL355 datasheet, Table 8: ADXL354 Pin Function Descriptions.

I grouped each physical pin exactly once, using the datasheet pin name/function as the source of truth.

Recommended pin groups

Table

Group	Pins	Common function
Power	5 `VDDIO`; 8 `V1P8DIG`; 10 `V1P8ANA`; 11 `VSUPPLY`	Supply rails / regulator-related supplies
Ground	6 `VSSIO`; 9 `VSS`	Digital and analog ground returns
Analog Outputs	4 `TEMP`; 12 `XOUT`; 13 `YOUT`; 14 `ZOUT`	Sensor output signals: temperature plus X/Y/Z acceleration outputs
Control / Mode Select	1 `RANGE`; 7 `STBY`	Device configuration / operating-mode selection
Self Test	2 `ST1`; 3 `ST2`	Self-test control inputs

Per-pin classification

Table

Pin No.	Mnemonic	Section	Pin Group	Suggested Pin Type	Notes
1	`RANGE`	Control	Control / Mode Select	Input	Range selection pin; tied to ground or `VDDIO` depending range selection.
2	`ST1`	Control	Self Test	Input	Enables self-test mode; force low when not in self-test mode.
3	`ST2`	Control	Self Test	Input	Activates electromechanical self-test actuation; force low when not in self-test mode.
4	`TEMP`	Analog	Analog Outputs	Output	Temperature sensor output.
5	`VDDIO`	Power	Power	Power In	Digital interface supply voltage.
6	`VSSIO`	Ground	Ground	Ground	Digital ground.
7	`STBY`	Control	Control / Mode Select	Input	Standby/measurement mode selection.
8	`V1P8DIG`	Power	Power	Power In	Digital supply; requires decoupling capacitor.
9	`VSS`	Ground	Ground	Ground	Analog ground.
10	`V1P8ANA`	Power	Power	Power In	Analog supply; requires decoupling capacitor.
11	`VSUPPLY`	Power	Power	Power In	Main supply; can feed internal LDO regulators for the 1.8 V rails.
12	`XOUT`	Analog	Analog Outputs	Output	X-axis analog output.
13	`YOUT`	Analog	Analog Outputs	Output	Y-axis analog output.
14	`ZOUT`	Analog	Analog Outputs	Output	Z-axis analog output.

Notes

I did not duplicate any pin across groups.
I kept TEMP with the analog outputs because it is an analog sensor output, not a power/control pin.
I kept ST1 and ST2 separate from general control because the datasheet gives them a shared self-test function.
I grouped RANGE and STBY together as mode/configuration control pins.
The package is 14 pins; no exposed pad or no-connect pin was identified in the extracted ADXL354 pin function table.

Description

Accelerometer X, Y, Z Axis ±2g, 4g 1.5kHz 14-CLCC (6x6)

General Description

The ADXL354BEZ is a low noise, low drift, low power, 3-axis MEMS accelerometer designed for high precision sensing applications. It provides analog voltage outputs proportional to acceleration along the X, Y, and Z axes. The device is optimized for applications requiring high resolution and long-term stability, including structural health monitoring, condition monitoring, tilt sensing, and seismic measurements.

The sensor features excellent temperature stability, minimal offset drift, and selectable measurement ranges. Its very low noise density makes it suitable for vibration analysis and other sensitive measurement environments.

Key Features 3-axis MEMS accelerometer with analog outputs Selectable measurement ranges of ±2 g, ±4 g, and ±8 g Ultra-low noise density of approximately 20 µg/√Hz Low offset drift across temperature Low power consumption of approximately 150 µA (typical) High resolution and measurement stability Integrated temperature sensor output Hermetically sealed package for improved environmental robustness Functional Description

The ADXL354BEZ measures acceleration using capacitive MEMS sensing elements arranged along three orthogonal axes. When acceleration is applied, the internal sensing structure experiences displacement, causing a change in capacitance. This change is converted into an analog voltage output for each axis.

Each axis produces a continuous-time analog signal, allowing direct interfacing with external analog-to-digital converters or signal conditioning circuits. Internal signal conditioning ensures low noise performance and stable output behavior.

Electrical Characteristics (Typical)

The device operates with a supply voltage ranging from 2.25 V to 3.6 V. Typical supply current during normal operation is approximately 150 µA. The noise density for all three axes is around 20 µg/√Hz. The bandwidth is user selectable and can reach up to approximately 1.5 kHz. The output signals are analog and ratiometric with respect to the supply voltage.

Mechanical Characteristics

The ADXL354BEZ is housed in a compact leadless chip carrier (LCC) package with approximate dimensions of 5 mm by 5 mm. It is designed for surface-mount installation. The sensing axes are aligned orthogonally to provide accurate three-dimensional acceleration measurement.

Performance Characteristics High resolution suitable for precision sensing applications Low temperature coefficient and minimal drift over time High linearity across the full-scale measurement range Excellent long-term stability Low cross-axis sensitivity for improved accuracy Pin Configuration Overview

The device includes power supply and ground connections, along with individual analog outputs for each axis labeled XOUT, YOUT, and ZOUT. A self-test pin is provided for functionality verification, and a temperature output pin allows monitoring of internal device temperature.

Operating Conditions

The device is designed to operate over a temperature range from −40°C to +125°C. Storage temperature ranges from −65°C to +150°C. The recommended supply voltage range is 2.25 V to 3.6 V.

Applications Structural health monitoring Industrial condition monitoring Seismic and geophysical sensing Tilt and inclination measurement Platform stabilization systems Vibration analysis Advantages Extremely low noise performance for high sensitivity applications Stable operation across wide temperature ranges Simple analog interface without the need for digital communication protocols Robust packaging suitable for harsh environments Compliance and Reliability

The ADXL354BEZ is RoHS compliant and designed for industrial-grade applications. It offers high reliability and long-term performance stability in demanding operating conditions.
