Product details
Overview
ADXL001-500BEZ-R7 from Analog Devices is a high-bandwidth, ±500 g single-axis MEMS accelerometer with 22 kHz resonant frequency, 3.3–5 V supply operation, 2.2 mV/g sensitivity at 3.3 V, and low noise density of 4.25 mg/√Hz (10 Hz–400 Hz). It delivers ratiometric output, full differential signal processing, and integrated self-test for vibration monitoring in harsh industrial environments.
For engineers reviewing the ADXL001-500BEZ-R7 datasheet, ADXL001-500BEZ-R7 pinout, ADXL001-500BEZ-R7 application, or ADXL001-500BEZ-R7 equivalent, this page provides verified specifications, package mapping, functional pin roles, real-world use cases, and validated alternative options for shock detection, condition-based maintenance, and high-g instrumentation design.
Technical Context
The ADXL001-500BEZ-R7 implements a fully differential SOI-MEMS sensor structure with electrically isolated but mechanically coupled sensing cells, enabling zero-force feedback conditioning and high EMI/RFI immunity. Its 125 kHz internal clock drives demodulation, and its ratiometric output scales linearly with supply voltage - zero-g bias = VS/2, sensitivity ∝ VS.
Self-test activation applies electrostatic force to the proof mass, producing a calibrated output delta (62 mV typical at 3.3 V, 217 mV at 5 V) that validates the entire electromechanical signal chain - sensor, modulator/demodulator, amplifier, and output stage - across −40°C to +125°C.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Full-Scale Range | ±500 g - supports high-shock event capture without clipping in impact testing or weapon systems. |
| Sensitivity (3.3 V) | 2.2 mV/g - enables direct interface to 16-bit ADCs with ≥2.2 V full-scale range for <1 LSB error. |
| Noise Density | 4.25 mg/√Hz - ensures resolution better than 0.1 g RMS in 100 Hz bandwidth for precision vibration analysis. |
| −3 dB Bandwidth | 32 kHz - preserves transient fidelity for ultrasonic structural health monitoring and engine knock detection. |
| Resonant Frequency | 22 kHz - places mechanical resonance safely above usable signal band, minimizing phase distortion. |
| Supply Current | 2.5 mA typical (3.3 V) - allows battery-powered deployment in portable diagnostic tools with >1-year runtime. |
| Operating Temp | −40°C to +125°C - qualified for under-hood automotive, downhole oil & gas, and military-grade embedded systems. |
Pinout & Package
ADXL001-500BEZ-R7 uses an 8-terminal hermetic ceramic LCC (E-8-1), 0.197" × 0.197" body, 0.070" nominal height, RoHS-compliant matte tin plating (Option 1) or gold plating (Option 2).
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1, 2, 5 | DNC (Do Not Connect) | Internally unused; must remain floating - no routing or soldering permitted. |
| 3 | COM | Common reference node for internal circuitry; connects to system ground for stable bias point. |
| 4 | ST | Logic-controlled self-test input; TTL-compatible (VIH = 2.1 V min @ 3.3 V); activates full-sensor displacement verification. |
| 6 | XOUT | Differential-to-single-ended output; ratiometric voltage proportional to x-axis acceleration (2.2 mV/g @ 3.3 V). |
| 7, 8 | VDD / VDD2 | Redundant power inputs - both pins must be tied together and decoupled with 0.1 µF ceramic capacitor. |
Key Features
| Feature | Design Value |
|---|---|
| Velocity preservation during overload | Maintains accurate velocity integration even under >4000 g shock - critical for post-impact motion reconstruction. |
| Complete electromechanical self-test | Validates sensor element, signal chain, and amplifier in one digital command - eliminates need for external shaker calibration. |
| High EMI/RFI immunity | Differential architecture rejects >60 dB common-mode noise - operates reliably near inverters, RF transmitters, and motor drives. |
| Ratiometric output | Zero-g offset = VS/2 and sensitivity ∝ VS - simplifies system-level calibration when using shared ADC reference. |
| DC-coupled frequency response | Measures static tilt and low-frequency vibration (0 Hz to 32 kHz) - enables dual-use in inertial navigation and machine health monitoring. |
Applications
| Vibration Monitoring | Shock Detection |
|---|---|
Use Scenario: Continuous monitoring of bearing vibration in wind turbine gearboxes operating at 10–20 kHz. IC Role / Device Role / Timing Role: Primary x-axis acceleration sensor capturing high-frequency resonance modes indicative of early-stage pitting or spalling.

IC Role / Device Role / Timing Role: Embedded sensor detecting abnormal deceleration spikes indicating die misalignment or material jam. Use Value: −40°C to +125°C rating survives oil-cooled press environments; self-test verifies functionality before each production cycle. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar high-bandwidth accelerometer applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| ADXL1002BCPZ-RL7 | ±50 g range, 21 kHz bandwidth, 2.5 V supply only, lower noise (2.5 mg/√Hz), same LCC-8 package. | Optimized for lower-g, higher-resolution vibration analysis (e.g., motor bearing fault detection), not shock events. | Select when full-scale range ≤ ±50 g suffices and ultra-low noise is prioritized over dynamic range. |
| ADXL372BCCZ-RL7 | ±200 g range, 3.2 kHz bandwidth, 1.8 V supply, integrated digital output (SPI), 3.5 µA standby current. | Targeted at battery-powered wearable impact monitors; lacks analog ratiometric output and DC coupling. | Select for ultra-low-power, digitally interfaced applications where bandwidth < 10 kHz is acceptable. |
Compared with ADXL1002BCPZ-RL7 and ADXL372BCCZ-RL7, the ADXL001-500BEZ-R7 uniquely combines ±500 g range, 32 kHz bandwidth, DC-coupled analog output, and extended temperature operation - making it the only option for high-g, wideband, analog-integrated industrial shock and vibration sensing.

FAQ
What is the supply voltage range for reliable operation of the ADXL001-500BEZ-R7?
The ADXL001-500BEZ-R7 operates reliably from 3.135 V to 6.0 V DC. It is fully specified at 3.3 V and 5.0 V, with performance parameters including zero-g offset (VS/2), sensitivity (∝ VS), and self-test delta (∝ VS³) scaling accordingly. Operation outside this range risks permanent damage per absolute maximum ratings.
Does the ADXL001-500BEZ-R7 support true DC-coupled acceleration measurement?
Yes, the ADXL001-500BEZ-R7 provides true DC-coupled response down to 0 Hz, enabling static tilt sensing and low-frequency vibration analysis. Its fully differential architecture and ratiometric output maintain accuracy across temperature and supply variations, making ADXL001-500BEZ-R7 suitable for inertial stabilization and structural monitoring applications.
How does the self-test function verify sensor integrity in the ADXL001-500BEZ-R7?
The ADXL001-500BEZ-R7 self-test applies electrostatic force to the proof mass via the ST pin, generating a calibrated output delta (62 mV typ @ 3.3 V) that exercises the full signal chain - mechanical sensor, modulation/demodulation, amplification, and output stage. This confirms end-to-end functionality without external equipment, and ADXL001-500BEZ-R7 performs this test across its full −40°C to +125°C operating range.
What is the recommended PCB layout practice for minimizing noise on the ADXL001-500BEZ-R7 XOUT signal?
To minimize noise on the ADXL001-500BEZ-R7 XOUT signal, place a 1000 pF ceramic capacitor directly between XOUT and COM close to the device. Use a solid ground plane beneath the sensor, route XOUT away from noisy traces (especially clocks and switching regulators), and avoid vias in the XOUT path. These practices leverage ADXL001-500BEZ-R7's differential architecture while suppressing high-frequency interference.
Is the ADXL001-500BEZ-R7 pin-compatible with other ADXL001 variants like the ADXL001-70BEZ-R7?
Yes, all ADXL001 variants - including ADXL001-500BEZ-R7, ADXL001-250BEZ-R7, and ADXL001-70BEZ-R7 - share identical 8-terminal LCC (E-8-1) packaging and pinout. They differ only in full-scale range, sensitivity, noise, and self-test response; no PCB redesign is required when upgrading or downgrading within the ADXL001 family.
