Product details
Overview
ADIS16470AMLZ from Analog Devices is a miniature, factory-calibrated MEMS inertial measurement unit (IMU) integrating triaxial gyroscope (±2000°/sec), triaxial accelerometer (±40 g), and on-board signal conditioning. It delivers 8°/hr in-run bias stability, 0.008°/sec/√Hz rate noise density, and 13 μg accelerometer bias stability for high-accuracy motion sensing in navigation-grade industrial systems.
For engineers reviewing the ADIS16470AMLZ datasheet, ADIS16470AMLZ pinout, ADIS16470AMLZ application, or ADIS16470AMLZ equivalent, this page provides verified technical context, SPI interface timing constraints, delta-angle/delta-velocity output formats, factory calibration scope (−10°C to +75°C), and BGA-44 mechanical shock survivability (2000 g).
Technical Context
The ADIS16470AMLZ implements a dual-stage digital signal chain: gyroscopes sample at 4100 Hz and accelerometers at 4000 Hz, both decimated to a synchronized 2000 SPS output rate via Bartlett window FIR filtering and averaging/decimating stages. Factory calibration applies orthogonal alignment correction, linear-g compensation (gyro), and point-of-percussion correction (accelerometer), stored in nonvolatile flash memory.
It uses SPI Mode 3 (CPOL = 1, CPHA = 1) with 16-bit register addressing, supports external sync modes (direct/pulse/scaled/output), and includes hardware reset recovery (193 ms), data-ready (DR) signaling, and on-demand self-test for both inertial sensors and flash memory.

Key Features
| Feature | Design Value |
|---|---|
| Factory Calibration | Full sensitivity, bias, axial misalignment, linear-g (gyro), and point-of-percussion (accel) corrections applied across −10°C to +75°C - eliminates need for field calibration in most industrial deployments. |
| Delta-Angle/Delta-Velocity Outputs | Integrated angular displacement (°) and linear velocity change (m/sec) outputs - reduces host MCU computational load in navigation algorithms. |
| On-Demand Self-Test | Separate commands verify inertial sensor functionality and flash memory integrity - enables runtime diagnostics in safety-critical autonomous systems. |
| Programmable Filtering | Bartlett window FIR and configurable decimation (via DEC_RATE register) allow trade-off between bandwidth (up to 550 Hz gyro / 600 Hz accel) and noise reduction. |
| Single-Supply Operation | 3.0 V to 3.6 V operation with 42–50 mA normal-mode current - simplifies power design versus dual-supply IMUs and avoids level-shifting circuitry. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar inertial measurement applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| ADIS16475-3AMLZ | Higher gyro bias stability (2°/hr vs. 8°/hr), wider temp range (−40°C to +105°C), same BGA-44 package and SPI interface. | Targeted at aerospace and defense where ultra-low drift is mandatory; requires tighter thermal management due to higher power. | Select ADIS16475-3AMLZ when <2°/hr gyro bias stability is required and extended temperature operation justifies cost premium. |
| ICM-20948 | Lower-cost 9-DoF IMU (gyro/accel/mag), no factory calibration, 16-bit outputs only, 3.3 V supply, QFN-24 package. | Suitable for consumer drones and wearables where cost and size dominate; lacks navigation-grade stability and temperature compensation. | Choose ICM-20948 for cost-sensitive, non-safety-critical applications where system-level calibration is feasible. |
Compared with ADIS16470AMLZ, ADIS16475-3AMLZ offers superior drift performance and extended temperature capability but at higher cost and power, while ICM-20948 provides compact size and lower price but requires full system-level calibration and delivers lower stability metrics.

FAQ
What is the factory calibration temperature range for the ADIS16470AMLZ?
The ADIS16470AMLZ undergoes full factory calibration across −10°C to +75°C, covering sensitivity, bias, axial misalignment, linear-g effect (gyro), and point-of-percussion (accelerometer). These corrections are stored in on-chip flash and applied automatically during operation, enabling accurate performance without user calibration in that range. The ADIS16470AMLZ operates from −25°C to +85°C, with specifications guaranteed at TC = 25°C.
Does the ADIS16470AMLZ support external synchronization, and what modes are available?
Yes, the ADIS16470AMLZ supports external synchronization via the SYNC pin (J3) with four configurable modes: direct, pulse, scaled, and output. These are selected using bits [4:2] of the MSC_CTRL register. Direct and pulse modes accept external clocks (1.9–2.1 kHz typical) to align internal sampling to host system timing, enabling deterministic multi-sensor synchronization in distributed control systems.
What is the meaning of delta-angle and delta-velocity outputs in the ADIS16470AMLZ?
The ADIS16470AMLZ provides integrated delta-angle (in degrees) and delta-velocity (in meters/sec) outputs - computed internally by integrating raw gyroscope and accelerometer data over each 500 μs sample period (2000 SPS). These outputs reduce host processor computation load in navigation algorithms and improve timing determinism compared to integrating raw sensor streams in firmware.
How does the ADIS16470AMLZ handle self-test, and what components can be verified?
The ADIS16470AMLZ supports two independent on-demand self-tests: one for inertial sensors (gyros and accelerometers) and another for flash memory. Initiated via the GLOB_CMD register (Bit 2 for sensors, Bit 4 for flash), each test executes in ≤14 ms (sensor) or ≤32 ms (flash) and reports pass/fail status in diagnostic registers. This enables runtime health verification in safety-aware industrial and autonomous systems without disrupting normal operation.
What are the power supply requirements and current consumption of the ADIS16470AMLZ?
The ADIS16470AMLZ operates from a single 3.0 V to 3.6 V supply, drawing 42–50 mA in normal mode at VDD = 3.3 V. During power-on start-up or hardware reset, supply current transients may reach 250 mA for brief intervals. The device includes 8 VDD and 24 GND balls in its BGA-44 package to maintain stable voltage distribution and minimize noise coupling across analog and digital domains.
