Product details
Overview
ADXC1500WBRGZ-RL from Analog Devices is a monolithic MEMS inertial sensor integrating a yaw-rate gyroscope and dual-axis (X/Y) accelerometer in a single 16-lead inverted cavity SOIC package. It delivers ±32 g acceleration range, ±2°/sec gyroscope null stability over temperature, 0.1°/sec rms gyroscope noise at 35.6 Hz, 6 kHz data update rate, and SPI interface with 4-bit CRC - designed for electronic stability control (ESC) systems in automotive chassis applications.
For engineers reviewing the ADXC1500WBRGZ-RL datasheet, ADXC1500WBRGZ-RL pinout, ADXC1500WBRGZ-RL application, or ADXC1500WBRGZ-RL equivalent, key selection considerations include its automotive qualification (−40°C to +105°C), linear acceleration rejection (0.03°/sec/g), dual-sensor co-location advantage, and fail-safe electromechanical self-test capability.
Technical Context
The ADXC1500WBRGZ-RL implements separate Σ-Δ modulators per sensor axis (X/Y accelerometer, Z-gyroscope), each with dedicated analog front-ends, band-pass filtering, and high-voltage generation for MEMS drive. Temperature compensation is applied in real time using an on-die sensor and NVM-trimmed calibration coefficients.
Its SPI interface operates at up to 10 MHz with frame-synchronized MISO/MOSI/SCLK/CS, supports programmable filter response, and embeds 4-bit CRC per 16-bit data word. The integrated continuous self-test (CST) performs real-time electromechanical diagnostics on all MEMS elements without external stimulus.

Equivalent & Alternatives
The following parts are listed as comparable options for similar inertial sensing applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| ADXC1501WBRGZ-RL | Same die, different trim and calibration; specified for extended temperature range (−40°C to +125°C) and tighter null stability (±1.5°/sec). | Targeted at engine bay or transmission-mounted ESC modules where ambient exceeds +105°C. | Select ADXC1501WBRGZ-RL only if operating above +105°C is required; otherwise ADXC1500WBRGZ-RL meets standard ESC under-hood specs. |
| MPU-6500 | Consumer-grade 6-axis IMU (3-axis gyro + 3-axis accel); no automotive qualification, no CST, no linear acceleration rejection spec. | Intended for drones, wearables, and non-safety-critical motion sensing - not suitable for ESC or ASIL-relevant functions. | MPU-6500 lacks required automotive qualification, fail-safe features, and environmental robustness; use only in non-automotive contexts. |
Compared with ADXC1501WBRGZ-RL, the ADXC1500WBRGZ-RL offers cost-optimized performance for standard automotive under-hood ESC deployment, while MPU-6500 serves entirely different market segments with no functional or safety equivalence.

FAQ
What is the operating temperature range of the ADXC1500WBRGZ-RL?
The ADXC1500WBRGZ-RL is qualified for operation from −40°C to +105°C. This range covers typical automotive under-hood environments and aligns with AEC-Q100 Grade 2 requirements. The device uses on-die temperature sensing and NVM-trimmed calibration to maintain bias and sensitivity stability across this full span, with ±2°/sec gyroscope null drift and ±30 mg accelerometer bias variation.
Does the ADXC1500WBRGZ-RL support both 3.3 V and 5 V supplies?
Yes, the ADXC1500WBRGZ-RL supports dual-supply operation: AVDD and DVDD can be independently set to either 3.3 V or 5 V. VSIO is separately configurable from 1.8 V to 5 V to match host MCU I/O voltage. This flexibility allows direct integration into legacy 5 V ECUs or modern 3.3 V domains without external level shifters or regulators.
How does the ADXC1500WBRGZ-RL handle electromagnetic interference in automotive environments?
The ADXC1500WBRGZ-RL uses a 16-lead inverted cavity SOIC package that shields the MEMS die from radiated EMI. Its analog and digital grounds are separated internally and require single-point connection per layout guidelines. Combined with differential AFE inputs referenced to VCM and on-chip high-voltage generation, this design achieves robust operation in high-noise chassis harness environments.
What fault detection mechanisms are implemented in the ADXC1500WBRGZ-RL?
The ADXC1500WBRGZ-RL includes SPI CRC (4-bit per 16-bit word), internal sensor data integrity checks, and a fully integrated continuous self-test (CST) that verifies MEMS element functionality in real time. These features collectively support ASIL-B diagnostic coverage per ISO 26262 and eliminate reliance on external test hardware or periodic manual calibration.
Is the ADXC1500WBRGZ-RL pin-compatible with other members of the ADXC1500 family?
Yes, all ADXC1500 variants-including ADXC1500WBRGZ-RL and ADXC1501WBRGZ-RL-share identical pinout, package, and footprint. Differences are limited to internal calibration, temperature range specification, and null stability performance; no PCB redesign is needed when migrating between these variants for qualification or thermal margin adjustments.
