Product details
Overview
ADXC1500AWBRGZ-RL from Analog Devices is a monolithic MEMS yaw rate gyroscope and dual-axis (X/Y) accelerometer in a single 16-lead inverted cavity SOIC package, operating from 3.3 V or 5 V, delivering ±32 g acceleration range, ±2°/sec gyroscope null stability over temperature, and 6 kHz data update rate for automotive electronic stability control systems.
For engineers reviewing the ADXC1500AWBRGZ-RL datasheet, ADXC1500AWBRGZ-RL pinout, ADXC1500AWBRGZ-RL application, or ADXC1500AWBRGZ-RL equivalent, key selection criteria include SPI interface with 4-bit CRC, −40°C to +105°C automotive qualification, linear acceleration rejection (0.03°/sec/g), dual-sensor co-location accuracy, and integrated electromechanical self-test capability.
Technical Context
The ADXC1500AWBRGZ-RL integrates separate XY accelerometer and Z-axis gyroscope sensor dies with dedicated sigma-delta modulators, band-pass filtering, and high-voltage generation for Coriolis sensing. Temperature compensation is applied to both bias and sensitivity using an on-die thermal sensor and NVM-trimmed calibration coefficients.
SPI communication uses four-wire mode (CS, SCLK, MOSI, MISO) with 16-bit data words and 4-bit CRC per frame. Internal fault detection monitors sensor health, register integrity, and power supply levels, while continuous self-test (CST) validates MEMS element functionality without external stimulus.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Acceleration Range | ±32 g - supports chassis-level crash and pothole shock events without saturation |
| Gyroscope Null Stability | ±2°/sec over −40°C to +105°C - enables ESC system bias drift <0.5°/sec during full automotive thermal cycling |
| Accelerometer Bias Stability | ±30 mg over temperature - ensures <0.3% FS error in lateral/longitudinal acceleration measurement across operating range |
| Noise Density (Accel) | 2.5 mg rms at 35.6 Hz - provides <0.05° tilt resolution when used with complementary filter fusion |
| Noise Density (Gyro) | 0.1°/sec rms at 35.6 Hz - supports yaw rate detection down to 0.02°/sec in low-dynamic maneuvers |
| Linear Accel Rejection | 0.03°/sec/g - suppresses vibration-induced gyro output errors during rough-road operation |
| Data Rate | 6 kHz - enables real-time closed-loop ESC actuation with <167 µs sampling interval |
Pinout & Package
ADXC1500AWBRGZ-RL is housed in a 16-lead inverted cavity SOIC package (body size 10.3 mm × 7.5 mm, lead pitch 1.27 mm), optimized for EMI immunity in automotive under-hood environments.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| CS | Chip Select Input | Active-low SPI slave enable; must be held low for full frame transmission (16-bit + 4-bit CRC) |
| SCLK | Serial Clock Input | Master-generated clock up to 10 MHz; synchronizes all SPI data transfers |
| MOSI | Master Out, Slave In | Configures registers (e.g., filter settings, self-test enable) and initiates read commands |
| MISO | Master In, Slave Out | Outputs 16-bit sensor data + 4-bit CRC; supports daisy-chain readout in multi-sensor systems |
| VSA / VSD | Analog/Digital Supply | VSA powers analog front-end; VSD powers digital logic; independent regulation prevents coupling noise |
| AVDD / DVDD | Analog/Digital Power | Accepts 3.3 V or 5 V; internal regulators derive stable core voltages for MEMS and logic |
| AGND / DGND | Analog/Digital Ground | Separate ground planes required to maintain <10 µV RMS noise floor on sensor outputs |
| VSIO | I/O Voltage Reference | Defines logic threshold for SPI interface; matches host MCU voltage (3.3 V or 5 V) |
| VCM | Common-Mode Reference | Bias point for differential analog paths; critical for accelerometer signal chain DC accuracy |
| TPA / TPB | Test Pins | Factory-access only; used for wafer-level trim and final functional test; not user-connectable |
Key Features
| Feature | Design Value |

| SPI with 4-bit CRC | Ensures end-to-end data integrity for safety-critical ESC decisions; detects single-bit errors in transmitted sensor frames |
| Temperature-Compensated Bias & Sensitivity | Uses on-die thermal sensor and factory-trimmed NVM coefficients to hold bias drift within ±2°/sec (gyro) and ±30 mg (accel) |
| Robust EMI Packaging | Inverted cavity SOIC shields sensitive analog paths from radiated noise in 12 V automotive electrical environments |
Applications

Equivalent & Alternatives
The following parts are listed as comparable options for similar inertial sensing applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| ADXC1501AWBRGZ-RL | Same die and package; differs only in factory-programmed NVM configuration (default filter settings and CST behavior) | Targeted for chassis control variants requiring different bandwidth or self-test frequency | Select ADXC1501AWBRGZ-RL only if specific register defaults match OEM chassis control software stack |
| MPU-6500 | Consumer-grade 6-axis IMU; lacks automotive qualification, no linear acceleration rejection, no CST, 1 kHz max data rate | Suitable for non-safety prototyping only; not qualified for ESC or ASIL-relevant functions | Use MPU-6500 only for lab evaluation; ADXC1500AWBRGZ-RL is mandatory for production automotive safety systems |
Compared with ADXC1501AWBRGZ-RL, the ADXC1500AWBRGZ-RL offers identical hardware but distinct factory firmware-making it the default choice for standard ESC integration.

FAQ
What is the operating voltage range of the ADXC1500AWBRGZ-RL?
The ADXC1500AWBRGZ-RL operates from either 3.3 V or 5 V supply rails, with separate AVDD/DVDD pins accepting either voltage. Internal regulation ensures stable core voltages regardless of input choice, and VSIO sets I/O logic thresholds to match the host microcontroller's voltage level-enabling direct interfacing with both 3.3 V and 5 V MCUs without level shifters.
Does the ADXC1500AWBRGZ-RL support daisy-chained SPI configurations?
Yes, the ADXC1500AWBRGZ-RL supports daisy-chained SPI operation via its MISO pin, which can drive the MOSI of a downstream device. This allows multiple ADXC1500AWBRGZ-RL units to share a single CS line and clock, reducing MCU pin count in multi-axis or redundant sensor architectures-provided timing budgets accommodate cumulative propagation delay.
How does the continuous self-test (CST) function in the ADXC1500AWBRGZ-RL?
The ADXC1500AWBRGZ-RL implements an electromechanical continuous self-test that applies controlled electrostatic forces to each MEMS element during normal operation. It verifies sensor responsiveness, signal chain gain, and offset stability without interrupting data output or requiring external stimuli-providing real-time diagnostic coverage required for ISO 26262 ASIL-B compliant ESC systems.
Is the ADXC1500AWBRGZ-RL qualified for automotive applications?
Yes, the ADXC1500AWBRGZ-RL is fully qualified for automotive applications per AEC-Q100 Grade 2 (−40°C to +105°C) and supports functional safety development per ISO 26262. Its design includes built-in fault detection, CRC-protected SPI, and continuous self-test-all documented in the official ADXC1500 safety manual and supported by Analog Devices' automotive quality certification.
What is the significance of the inverted cavity SOIC package used in the ADXC1500AWBRGZ-RL?
The inverted cavity SOIC package of the ADXC1500AWBRGZ-RL places the MEMS die face-down inside a shielded cavity, minimizing parasitic capacitance and enhancing immunity to radiated EMI from automotive alternators, ignition systems, and switching regulators. This construction meets CISPR 25 Class 5 emission requirements and maintains sensor accuracy in noisy under-hood environments.
