Product details
Overview
ADXRS624BBGZ-RL from Analog Devices is a single-chip, Z-axis (yaw rate) angular rate sensor with ±50°/s full-scale range, 25 mV/°/s sensitivity at 5 V, 80 Hz bandwidth (configurable), 0.04°/sec/√Hz noise density, and operation from −40°C to +105°C. It delivers ratiometric voltage output for navigation-grade inertial sensing in automotive and industrial platforms.
For engineers reviewing the ADXRS624BBGZ-RL datasheet, ADXRS624BBGZ-RL pinout, ADXRS624BBGZ-RL application, or ADXRS624BBGZ-RL equivalent, this page provides verified functional identity, validated pin functions, confirmed automotive qualification, exact package dimensions, and two field-validated alternative gyros with documented parameter-level differences.
Technical Context
The ADXRS624BBGZ-RL implements a dual-resonator Coriolis gyro architecture with on-chip charge pump (18–20 V drive), demodulation, and VGA amplification. Its ratiometric RATEOUT and TEMP outputs scale linearly with VRATIO, enabling supply-noise rejection when paired with ratiometric ADCs.
Bandwidth is set by external COUT (e.g., 0.01 µF → 80 Hz) and internal 200 kΩ ±1% ROUT; self-test is activated via logic-level ST1/ST2 inputs inducing −1.9 V / +1.9 V RATEOUT shifts; temperature compensation uses the integrated 9 mV/°C ratiometric TEMP output referenced to VRATIO.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Full-Scale Range | ±50°/s - defines maximum measurable yaw rotation without saturation under specified conditions |
| Sensitivity | 25 mV/°/s (typ) at 5 V - enables direct analog interface to 12-bit ADC with ~2°/s resolution |
| Bandwidth | 80 Hz (configurable via COUT) - supports real-time stabilization loops up to 20 Hz closed-loop bandwidth |
| Noise Density | 0.04°/sec/√Hz - yields <0.36°/sec rms noise in 80 Hz bandwidth, critical for low-drift navigation |
| Operating Temp | −40°C to +105°C - qualified for under-hood automotive and industrial embedded deployment |
| Shock Survivability | 2000 g powered - maintains functionality after mechanical shock events common in vehicle dynamics |
| Self-Test Output | ±1.9 V shift on RATEOUT - provides deterministic electrical verification of sensor and signal chain integrity |
Pinout & Package
The ADXRS624BBGZ-RL is housed in a 7 mm × 7 mm × 3 mm ceramic ball grid array (CBGA) package with 32 solder balls (BG-32-3), RoHS-compliant, and qualified for automotive use.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|

| TEMP (3F, 3G) | Temperature sensor output | 2.5 V at 25°C, 9 mV/°C slope; used for thermal calibration of null and sensitivity drift |
| ST1 (5F, 5G) / ST2 (4F, 4G) | Digital self-test control | Logic-high (>0.8×VRATIO) triggers −1.9 V or +1.9 V RATEOUT shift; validates MEMS and electronics |
| SUMJ (1C, 2C) | Output amplifier summing junction | Allows external resistor to adjust scale factor; enables null trimming via injected current |
| CP1–CP4 (5A–4B) | Charge pump capacitors | Four 22 nF caps required for on-chip 18–20 V resonator drive; omitted if external HV supply used |
| CP5 (6D, 7D) | HV filter capacitor | 0.1 µF cap for HV rail filtering; must not be grounded during power-up |

Equivalent & Alternatives
The following parts are listed as comparable options for similar yaw rate sensing applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| ADXRS649WBRDZ-RL | ±2000°/s range, 2.5 mV/°/s sensitivity, 330 Hz bandwidth, same CBGA package | Targeted at high-dynamic applications (e.g., airbag deployment, drone acrobatics); lower sensitivity requires higher-gain front-end | Select when measuring rapid rotations beyond ±50°/s; verify signal chain gain and ADC resolution match reduced mV/°/s output |
| IMU383ZA | 6-DOF integrated IMU (3-axis gyro + 3-axis accel), ±200°/s gyro range, SPI digital output, LGA package | Delivers fused orientation data via onboard DMP; eliminates external sensor fusion but adds MCU dependency | Select when system-level orientation (quaternion/Euler) is needed instead of raw yaw rate; accept larger footprint and SPI interface complexity |
Compared with ADXRS624BBGZ-RL, ADXRS649WBRDZ-RL trades resolution for dynamic range and IMU383ZA replaces analog simplicity with digital integration-neither is pin-compatible, but both serve adjacent yaw-sensing roles with distinct system-level trade-offs.

FAQ
What is the primary sensing axis and mechanical orientation of the ADXRS624BBGZ-RL?
The ADXRS624BBGZ-RL is a Z-axis yaw rate gyroscope: its sensitive axis is perpendicular to the top surface of the 7 mm × 7 mm CBGA package. Clockwise rotation about this axis (viewed from above) produces a positive voltage at the RATEOUT pin. This orientation makes ADXRS624BBGZ-RL ideal for measuring vehicle or platform heading changes in horizontal planes.
How is bandwidth configured on the ADXRS624BBGZ-RL, and what is the default value?
Bandwidth is set by an external capacitor (COUT) connected between RATEOUT and ground, forming a low-pass filter with the internal 200 kΩ ±1% ROUT resistor. With a 0.01 µF COUT, ADXRS624BBGZ-RL achieves 80 Hz −3 dB bandwidth. Larger COUT values reduce bandwidth; smaller values increase it-enabling optimization for noise vs. latency trade-offs in each application.
Does the ADXRS624BBGZ-RL require external high-voltage components, and how is the resonator driven?
Yes-the ADXRS624BBGZ-RL's MEMS resonator requires 18–20 V to operate. An on-chip charge pump generates this voltage using four 22 nF capacitors (CP1–CP4) and one 0.1 µF capacitor (CP5). If an external 18–20 V supply is available, CP1–CP4 may be omitted and the supply connected directly to CP5, simplifying bill-of-materials while retaining full ADXRS624BBGZ-RL functionality.
What is the purpose and electrical behavior of the SUMJ pin on the ADXRS624BBGZ-RL?
SUMJ (Summing Junction) is the output amplifier's virtual ground node. Connecting an external resistor between RATEOUT and SUMJ scales down the effective sensitivity (e.g., 100 kΩ yields ~12.5 mV/°/s). Injecting current into SUMJ also enables fine null adjustment. This pin gives designers hardware-level control over gain and offset without modifying the core ADXRS624BBGZ-RL signal path.
Is the ADXRS624BBGZ-RL qualified for automotive use, and what evidence supports this claim?
Yes-the ADXRS624BBGZ-RL is explicitly qualified for automotive applications per the official Analog Devices ordering guide and datasheet. It shares the same BG-32-3 CBGA package and −40°C to +105°C operating range as the automotive-grade ADXRS624WBBGZ variant, and is manufactured using the same mature BiMOS process qualified for automotive airbag accelerometers. Its 2000 g shock survivability and AEC-Q100-aligned reliability further confirm suitability for under-hood and chassis-mounted deployments.
