Product details
Overview
ADXC1501AWBRGZ-RL from Analog Devices is a monolithic MEMS inertial sensor combining a yaw-rate gyroscope and a 3-axis ±32 g accelerometer in a single 16-lead SOIC package. It delivers ±30 mg accelerometer bias stability and ±2°/sec gyroscope null stability over −40°C to +105°C, with SPI output, 6 kHz update rate, and automotive qualification for chassis control systems.
For engineers reviewing the ADXC1501AWBRGZ-RL datasheet, ADXC1501AWBRGZ-RL pinout, ADXC1501AWBRGZ-RL application, or ADXC1501AWBRGZ-RL equivalent, key selection considerations include its dual-sensor integration, temperature-compensated bias/sensitivity, 0.1°/sec rms gyroscope noise at 35.6 Hz, 2.5 mg rms accelerometer noise, and robust electromechanical self-test capability.
Technical Context
The ADXC1501AWBRGZ-RL integrates two independent MEMS sensor dies - XY/gyroscope and Z-accelerometer - with dedicated sigma-delta modulators, band-pass filtering, and high-voltage generation for Coriolis drive. Its internal temperature sensor enables real-time compensation of bias and sensitivity drift across the full −40°C to +105°C range.
SPI interface operates with 16-bit data words and 4-bit CRC for fault coverage; continuous self-test (CST) validates MEMS element health during runtime. Linear acceleration rejection of 0.03°/sec/g ensures gyroscope accuracy under shock/vibration, while accelerometer signal chain withstands ±32 g overload without saturation.

Equivalent & Alternatives
The following parts are listed as comparable options for similar inertial sensing applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| ADXC1502AWBRGZ-RL | Same package and pinout; differs in gyroscope range (±150°/sec vs. ±300°/sec) and accelerometer range (±16 g vs. ±32 g). | Targeted at cost-sensitive chassis control where lower dynamic range suffices; not suitable for high-G ESC or crash recording. | Select ADXC1502AWBRGZ-RL only when system-level angular rate and acceleration excursions remain within its reduced full-scale limits. |
| MPU-6050 | Consumer-grade 6-axis IMU; lacks automotive qualification, temperature compensation, CST, and ±32 g overload capability. | Intended for mobile/wearable use; unsuitable for safety-critical automotive functions due to missing fail-safe features and AEC-Q100 compliance. | MPU-6050 may serve prototyping but cannot replace ADXC1501AWBRGZ-RL in production automotive systems requiring functional safety support. |
Compared with ADXC1501AWBRGZ-RL, ADXC1502AWBRGZ-RL offers lower range and cost for non-safety chassis roles, while MPU-6050 lacks automotive qualification, overload tolerance, and run-time self-test-making neither a drop-in replacement but only context-specific alternatives.

FAQ
What is the primary function of the ADXC1501AWBRGZ-RL?
The ADXC1501AWBRGZ-RL is a monolithic MEMS inertial sensor that simultaneously measures yaw rate (±300°/sec) and 3-axis acceleration (±32 g). It integrates temperature compensation, continuous self-test, and SPI output to serve as a core sensing element in automotive electronic stability control and chassis control systems. Its design prioritizes accuracy, reliability, and functional safety compliance under harsh environmental conditions.
Does the ADXC1501AWBRGZ-RL support both 3.3 V and 5 V operation?
Yes, the ADXC1501AWBRGZ-RL supports dual-supply operation at either 3.3 V or 5 V. This flexibility allows seamless integration into diverse automotive ECUs with varying power domain architectures. The device uses internal regulation to generate required bias voltages for MEMS elements and logic circuits, maintaining specified performance across both supply voltages without external component changes.
What fail-safe mechanisms does the ADXC1501AWBRGZ-RL implement?
The ADXC1501AWBRGZ-RL implements multiple fail-safe mechanisms including a 4-bit CRC on all SPI data transmissions, internal fault detection routines for sensor data integrity, and a fully integrated continuous self-test (CST) that validates MEMS element health during normal operation. These features collectively support ASIL-B readiness and ensure reliable operation in safety-critical automotive applications such as ESC and chassis control.
Is the ADXC1501AWBRGZ-RL qualified for automotive use?
Yes, the ADXC1501AWBRGZ-RL is qualified for automotive applications per AEC-Q100 Grade 2 standards, covering operation from −40°C to +105°C. It is designed for under-hood and chassis-mounted deployment, featuring robust EMI performance via its 16-lead SOIC package and built-in protection against thermal shock, vibration, and mechanical overload-key requirements for electronic stability control and safety-critical vehicle systems.
How does the ADXC1501AWBRGZ-RL handle linear acceleration interference on the gyroscope?
The ADXC1501AWBRGZ-RL achieves 0.03°/sec/g linear acceleration rejection through advanced gyroscope sensor design and mechanical isolation. This specification means that for every 1 g of linear acceleration applied, the gyroscope output shifts by no more than 0.03°/sec-enabling accurate yaw-rate measurement even during high-G braking or cornering. This performance is validated across temperature and is integral to its use in electronic stability control systems.
