Product details
Overview
ADIS16475-2BMLZ from Analog Devices is a precision, miniature MEMS inertial measurement unit (IMU) integrating triaxial gyroscope (±500°/sec range), triaxial accelerometer (±8 g), delta angle/delta velocity outputs, factory-calibrated bias and alignment, and SPI interface - deployed in high-dynamic industrial navigation and autonomous vehicle stabilization systems.
For engineers reviewing the ADIS16475-2BMLZ datasheet, ADIS16475-2BMLZ pinout, ADIS16475-2BMLZ application, or ADIS16475-2BMLZ equivalent, this page delivers verified specifications including 2.5°/hr in-run bias stability, 0.15°/√hr angular random walk, 44-ball BGA package (11 mm × 15 mm × 11 mm), 2000 SPS output rate, and −40°C to +105°C operating temperature - all confirmed from Analog Devices Rev. D datasheet.
Technical Context
The ADIS16475-2BMLZ implements a dual-stage digital signal chain: gyroscopes sample at 4100 Hz and accelerometers at 4000 Hz, both decimated to 2000 SPS output via Bartlett window FIR filtering and averaging. Factory calibration applies temperature-compensated 3×3 matrix correction for sensitivity, bias, axis misalignment (±0.1°), and linear-g effects on gyros and point-of-percussion correction on accelerometers.
It supports four external sync modes (direct, pulse, scaled, output) via SYNC pin, programmable self-test (inertial sensors and flash), automatic/manual bias correction, and data-ready (DR) signaling - all controlled through SPI-accessible registers including MSC_CTRL and FILT_CTRL with nonvolatile flash storage (10,000 write cycles, 20-year retention at 85°C).
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Gyroscope Range | ±500°/sec - enables accurate angular rate capture in medium-dynamic applications like robotic arm control and stabilized camera gimbals. |
| In-Run Bias Stability | 2.5°/hr (1σ) - ensures minimal drift during extended operation without recalibration, critical for dead-reckoning navigation. |
| Angular Random Walk | 0.15°/√hr - defines low-frequency noise floor limiting orientation accuracy over short integration periods. |
| Accelerometer Range | ±8 g - supports high-shock environments including construction machinery and UAV takeoff/landing transients. |
| Output Rate | 2000 SPS - provides high temporal resolution for real-time closed-loop control in motion-critical systems. |
| Operating Temp | −40°C to +105°C - validated for under-hood automotive, industrial automation, and outdoor unmanned systems. |

| Package | 44-ball BGA, 11 mm × 15 mm × 11 mm - compact footprint with thermal resistance θJA = 158.2°C/W for FR4-08 PCBs. |
Pinout & Package
The ADIS16475-2BMLZ uses a 44-ball BGA package (ML-44-13) with 0.8 mm ball pitch, designed for reflow soldering on standard FR4 PCBs. Ground planes occupy 32 balls; six VDD balls provide low-impedance power distribution; dedicated SPI signals (CS, SCLK, DIN, DOUT), DR, SYNC, and RST enable deterministic timing and synchronization.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| CS, SCLK, DIN, DOUT | SPI Interface | Full-duplex serial communication at up to 2 MHz; supports burst reads and register configuration with tDAV = 25 ns DOUT validity. |
| DR | Data Ready Output | Active-low pulse synchronized to new 2000 SPS data availability - eliminates polling and enables precise acquisition timing. |
| SYNC | External Clock Input | Accepts 1.9–2.1 kHz clock for deterministic sampling alignment across distributed IMU networks. |
| RST | Hardware Reset | Active-low input requiring ≥1 µs pulse width; initiates 193 ms recovery with full register reset and calibration reload. |
| VDD (6 pins) | Power Supply | Distributed 3.0–3.6 V supply connections minimize IR drop and improve PSRR for analog sensor front-end stability. |
| GND (32 pins) | Reference Plane | Extensive ground ball array reduces impedance, suppresses EMI coupling, and stabilizes internal reference voltages. |
Key Features
| Feature | Design Value |
|---|---|
| Factory Calibration | Per-device 3×3 scale/alignment matrices and bias offsets stored in flash - eliminates system-level calibration effort and reduces integration time. |
| Delta Angle/Delta Velocity Outputs | Integrated angular displacement and linear velocity increments - directly usable for strapdown inertial navigation without host-side integration. |
| On-Demand Self-Test | Electromechanical excitation of MEMS structures validates sensor functionality pre-deployment - meets functional safety diagnostic coverage requirements. |
| Programmable FIR Filtering | Bartlett window filter configurable via FILT_CTRL register - balances noise reduction against latency for application-specific bandwidth trade-offs. |
| Temperature-Compensated Operation | Calibration valid across −40°C to +85°C; in-run bias stability and ARW specified at 25°C - ensures consistent performance in uncontrolled thermal environments. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar inertial measurement applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| ADIS16477-2BMLZ | Same 44-ball BGA package and pinout; adds integrated magnetometer (±8 gauss) and higher gyro bias stability (1.8°/hr). | Enables full 9-DOF AHRS without external compass; suited for magnetic-field-stable indoor navigation. | Select ADIS16477-2BMLZ when heading accuracy requires absolute yaw reference and magnetic interference is minimal. |
| ADIS16505-2BMLZ | Lower cost variant with reduced gyro bias stability (4.0°/hr), no delta-angle/delta-velocity outputs, and simplified calibration model. | Targeted at cost-sensitive stabilization where full inertial navigation capability is not required. | Choose ADIS16505-2BMLZ for gimbal or platform stabilization where long-term orientation hold is secondary to budget constraints. |
Compared with ADIS16475-2BMLZ, ADIS16477-2BMLZ adds magnetometer-based yaw fusion but increases BOM cost and magnetic susceptibility, while ADIS16505-2BMLZ sacrifices navigation-grade bias stability and delta-output convenience for price-sensitive motion feedback.

FAQ
What is the gyroscope dynamic range of the ADIS16475-2BMLZ?
The ADIS16475-2BMLZ has a gyroscope dynamic range of ±500°/sec, confirmed in Table 1 of the Rev. D datasheet. This range balances sensitivity and headroom for medium-dynamic applications such as robotic joint control and stabilized imaging platforms. It differs from the ±125°/sec (ADIS16475-1) and ±2000°/sec (ADIS16475-3) variants in the same family.
Does the ADIS16475-2BMLZ support external synchronization?
Yes, the ADIS16475-2BMLZ supports four external sync modes - direct, pulse, scaled, and output - via the SYNC pin, as defined in Register MSC_CTRL Bits[4:2]. This enables deterministic sampling alignment across multiple IMUs in distributed systems, with timing parameters including tSTDR = 256 µs and t1 = 5 µs for pulse mode.
What is the in-run bias stability specification for the ADIS16475-2BMLZ?
The ADIS16475-2BMLZ has an in-run bias stability of 2.5°/hr (1σ), per Table 1 of the Rev. D datasheet. This value reflects short-term bias repeatability during continuous operation and is critical for minimizing drift in inertial navigation solutions over tens of seconds without external aiding.
How many power supply pins does the ADIS16475-2BMLZ have, and what is their function?
The ADIS16475-2BMLZ has six dedicated VDD pins (A7, D6, E3, H1, J4, J5, K6 - note A7 is VDD per Table 5 correction) and 32 GND balls. These distributed supply connections reduce impedance, improve power supply rejection ratio (PSRR), and stabilize the analog front-end for low-noise inertial sensing across its −40°C to +105°C operating range.
Can the ADIS16475-2BMLZ perform self-test, and what does it verify?
Yes, the ADIS16475-2BMLZ supports on-demand self-test of both inertial sensors and flash memory via GLOB_CMD register commands. The inertial self-test electrostatically excites MEMS structures to validate mechanical integrity and signal chain functionality - a key diagnostic for functional safety compliance in industrial and automotive deployments.
