Product details
Overview
ADIS16475-1BMLZ from Analog Devices is a precision, miniature MEMS inertial measurement unit (IMU) integrating triaxial gyroscope (±125°/sec range), triaxial accelerometer (±8 g), delta angle/delta velocity outputs, factory-calibrated bias and alignment, and SPI interface - deployed in high-stability navigation systems for autonomous vehicles and industrial robotics.
For engineers reviewing the ADIS16475-1BMLZ datasheet, ADIS16475-1BMLZ pinout, ADIS16475-1BMLZ application, or ADIS16475-1BMLZ equivalent, key selection criteria include in-run bias stability (2°/hr), angle random walk (0.15°/√hr), axis misalignment (±0.1°), operating temperature (−40°C to +105°C), and 44-ball BGA package compatibility with industrial PCB layouts.
Technical Context
The ADIS16475-1BMLZ implements a dual-stage digital signal chain: gyroscopes sample at 4.1 kHz and accelerometers at 4.0 kHz, both decimated to 2000 SPS output rate via Bartlett window FIR filtering and averaging. Factory calibration applies 9-parameter matrix correction for gyroscope scale/alignment/linear-g effects and 12-parameter correction for accelerometer scale/alignment/point-of-percussion, all stored in on-chip flash memory.
It supports four external sync modes (direct, pulse, scaled, output) via SYNC pin, enables on-demand self-test of inertial sensors and flash memory, and provides programmable bias correction (automatic/manual) with data-ready (DR) signaling for deterministic acquisition timing - critical for closed-loop motion control and INS integration.
Key Specifications

Equivalent & Alternatives
The following parts are listed as comparable options for similar inertial sensing applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| ADIS16477-1BMLZ | Same package and pinout; higher-grade gyroscope (1.25°/hr bias stability, 0.08°/√hr ARW) and extended calibration temp range (−55°C to +105°C). | Targeted for aerospace-grade INS and military-grade navigation where long-term bias stability is critical. | Select ADIS16477-1BMLZ when bias stability <1.5°/hr and extended cold-start performance are required; otherwise ADIS16475-1BMLZ offers optimal cost/performance balance. |
| ADIS16505-1AMLZ | Smaller 24-pin LGA (14.2 × 21.0 × 4.0 mm); lower power (32 mA), same ±125°/sec range but reduced bias stability (3.5°/hr) and no delta outputs. | Designed for size- and power-constrained applications like handheld survey tools and portable mapping systems. | Choose ADIS16505-1AMLZ only when board space is severely limited and delta outputs are unnecessary; ADIS16475-1BMLZ retains superior stability and full INS feature set. |
Compared with ADIS16475-1BMLZ, ADIS16477-1BMLZ delivers measurable improvement in long-term orientation hold but at higher cost and power, while ADIS16505-1AMLZ trades stability and functionality for compactness - making ADIS16475-1BMLZ the balanced choice for industrial-grade autonomous systems requiring proven reliability and full-feature IMU capability.

FAQ
What is the gyroscope dynamic range of the ADIS16475-1BMLZ?
The ADIS16475-1BMLZ has a gyroscope dynamic range of ±125°/sec, as specified in the ADIS16475-1 variant. This range is optimized for high-accuracy attitude estimation in applications such as UAV stabilization and robotic platform control, where low-noise, low-drift performance outweighs wide-range capability. The part number suffix "-1" explicitly denotes this range configuration.
Does the ADIS16475-1BMLZ support external synchronization?
Yes, the ADIS16475-1BMLZ supports four external sync modes - direct, pulse, scaled, and output - via its SYNC input pin. These modes allow precise alignment of internal sampling to an external clock source (1.9–2.1 kHz), enabling deterministic data capture in time-synchronized systems such as distributed sensor networks or motion-triggered data logging. Configuration is controlled through the MSC_CTRL register Bits[4:2].
What is the meaning of "delta angle" and "delta velocity" outputs in the ADIS16475-1BMLZ?
The ADIS16475-1BMLZ provides integrated delta angle (Δθ) and delta velocity (Δv) outputs - representing angular displacement and linear velocity change per sample period - computed onboard using high-resolution 32-bit accumulators. These outputs reduce computational load on the host processor and improve numerical stability in inertial navigation algorithms compared to raw rate/acceleration data.
How does factory calibration improve system integration for the ADIS16475-1BMLZ?
Factory calibration of the ADIS16475-1BMLZ includes full 9-parameter gyroscope and 12-parameter accelerometer correction matrices (bias, scale, misalignment, linear-g, point-of-percussion), measured across −40°C to +85°C and stored in on-chip flash. This eliminates the need for customer-performed system-level calibration, reducing integration time and ensuring consistent performance across units and temperature ranges.
What is the operating temperature range of the ADIS16475-1BMLZ?
The ADIS16475-1BMLZ operates over −40°C to +105°C, validated for continuous use across this full range. Its calibration temperature range is −40°C to +85°C, and performance specifications (e.g., bias stability, noise) are guaranteed within that interval. Operation above +85°C maintains functionality but may exhibit increased bias drift beyond datasheet guarantees.
