Analog Devices Inc. ADXRS652BBGZ

Overview

ADXRS652BBGZ from Analog Devices is an industrial-grade Z-axis (yaw rate) angular rate sensor with ±250°/sec full-scale range, 7.04 mV/°/sec sensitivity at 5 V supply, and ratiometric voltage output referenced to VRATIO. It integrates a surface-micromachined MEMS resonator, on-chip charge pump, signal conditioning, temperature sensor, and dual digital self-test inputs in a single 7 mm × 7 mm × 3 mm CBGA package for platform stabilization and inertial measurement units.

For engineers reviewing the ADXRS652BBGZ datasheet, ADXRS652BBGZ pinout, ADXRS652BBGZ application, or ADXRS652BBGZ equivalent, key selection criteria include its 80 Hz bandwidth (set by external COUT), −40°C to +105°C operating range, 2000 g shock survivability, ratiometric output behavior, and 0.06 °/sec/√Hz noise density - all critical for high-reliability industrial motion sensing.

Technical Context

The ADXRS652BBGZ implements a dual-resonator Coriolis gyroscope architecture with electrostatic drive at ~14.5 kHz and capacitive pickoff, enabling high vibration rejection across wide frequencies. Its on-die charge pump generates 18–20 V from a 5 V supply to actuate the polysilicon dither frames, eliminating need for external high-voltage sources unless CP5 is used for direct HV input.

Signal conditioning includes AC amplification, demodulation, and VGA stages feeding RATEOUT (1B, 2A), while SUMJ (1C, 2C) provides access to the internal summing node for null adjustment or scale modification. The integrated temperature sensor (TEMP, 3F/3G) outputs 2.5 V at 25°C with ~9 mV/°C coefficient, supporting compensation algorithms without external sensors.

FAQ

What is the full-scale angular rate range of the ADXRS652BBGZ?

The ADXRS652BBGZ has a guaranteed full-scale range of ±250°/sec over its specified temperature range (−40°C to +105°C). While the device can tolerate up to ±300°/sec under certain conditions, the ±250°/sec specification ensures linearity, low nonlinearity (0.1% of FS), and guaranteed performance across all operating conditions. This range is optimized for industrial platform stabilization and IMU applications where precision yaw sensing is required without overspecifying bandwidth or noise.

How does the ADXRS652BBGZ achieve vibration rejection?

The ADXRS652BBGZ achieves high vibration rejection through its dual-resonator Coriolis gyroscope architecture. Two matched polysilicon sensing structures operate differentially, causing common-mode acceleration and vibration signals to cancel at the output stage. This design, combined with a 14.5 kHz mechanical resonant frequency far above typical vibration spectra, enables effective rejection across a wide frequency band - verified to handle 10 g sinusoidal vibration with minimal cross-axis coupling. The result is clean yaw rate output even in high-noise mechanical environments.

Can the ADXRS652BBGZ be used with a 3.3 V system?

The ADXRS652BBGZ requires a 5 V supply (4.75–5.25 V) for AVCC, VDD, and VRATIO; it is not rated for 3.3 V operation. However, its digital self-test inputs (ST1, ST2) accept logic levels referenced to VRATIO, so a 3.3 V microcontroller can drive them safely if VRATIO = 5 V and appropriate level-shifting or open-drain interface is used. For true 3.3 V compatibility, consider the ADXRS453 or ADXRS290 families - but note these lack the ADXRS652BBGZ's industrial temperature range and 2000 g shock rating.

What external components are mandatory for ADXRS652BBGZ operation?

Four 22 nF capacitors (for CP1–CP4), one 0.1 μF capacitor (for CP5), and one timing capacitor (COUT, typically 0.01 μF for 80 Hz bandwidth) are mandatory for ADXRS652BBGZ operation. Additionally, 100 nF decoupling capacitors are required on AVCC and VDD. The ADXRS652BBGZ will not function without these external components, as they enable the on-chip charge pump, set bandwidth, and stabilize internal voltage rails. No resistors are required for basic operation, though a 1.07 MΩ resistor between RATEOUT and SUMJ may be added to match ADXRS620 scale.

Is the ADXRS652BBGZ pin-compatible with other ADXRS gyroscopes?

Yes, the ADXRS652BBGZ is 100% pin, package, temperature, and function compatible with the automotive-grade ADXRS620 and ADXRS622 gyroscopes. All share the same 32-ball CBGA (BC-32-3) footprint, identical pin assignments (including RATEOUT, ST1, ST2, TEMP, VRATIO), and overlapping electrical specifications. This allows drop-in replacement in existing designs - though ADXRS652BBGZ lacks automotive qualification testing, making it ideal for industrial upgrades where cost and availability outweigh ASIL requirements.
