Replacement verdict
Compatible functional replacement candidate
The ADIS16405BMLZ and ADIS16448BMLZ are both six-degree-of-freedom inertial sensor modules from the Analog Devices ADIS1640x family, sharing the same SPI interface, 16-bit output resolution, and comparable form factor. While they are not identical in sensor range and dynamic performance, the ADIS16448BMLZ can serve as a functional replacement candidate for the ADIS16405BMLZ in applications where the extended gyroscope and accelerometer ranges are acceptable, subject to validation of the specific measurement requirements.

Key electrical and mechanical differences between the two devices
| Parameter | ADIS16405BMLZ | ADIS16448BMLZ | Why it matters |
|---|---|---|---|
| Gyroscope Dynamic Range | ±300 °/sec | ±1000 °/sec | Determines the maximum angular rate the IMU can measure without saturation; the higher range of the ADIS16448 suits higher-rate motion applications. |
| Accelerometer Dynamic Range | ±18 g | ±18 g | Sets the maximum acceleration measurable before clipping; both parts share the same range, so shock/vibration headroom is equivalent. |
| Magnetometer | Tri-axis, ±2.5 Gauss | Not included | The ADIS16405 integrates a magnetometer for heading/compass reference, while the ADIS16448 omits it, so magnetic heading capability is not substitutable. |
| Barometric Pressure Sensor | Not included | Included (300–1100 mbar) | The ADIS16448 adds a pressure sensor for altitude estimation, a function absent on the ADIS16405, affecting navigation use cases. |
| Gyroscope In-Run Bias Stability | ~0.007 °/sec (typical) | ~0.007 °/sec (typical) | Indicates low-frequency drift of the gyro; comparable stability means similar attitude-hold performance over time. |
| Interface | SPI | SPI | Both use a serial peripheral interface, so host-side digital integration is compatible across the two parts. |
| Supply Voltage | 3.0 V to 3.6 V | 3.0 V to 3.6 V | Identical supply requirements allow the same power rail design for either device. |
| Operating Temperature Range | −40 °C to +105 °C | −40 °C to +105 °C | Matching temperature ratings ensure equivalent environmental robustness for industrial and harsh-environment deployments. |
| Package | 24-lead MLP (module) | 24-lead MLP (module) | Same footprint and form factor simplify board-level drop-in substitution between the two modules. |

Frequently asked questions
What are the key differences between the ADIS16405BMLZ and the ADIS16448BMLZ?
Both are complete inertial measurement units (IMUs) in the same 23 mm × 23 mm × 23 mm module package, but they differ in sensor configuration and interface. The ADIS16405BMLZ integrates a triaxial gyroscope, triaxial accelerometer, and triaxial magnetometer, and provides a SPI interface. The ADIS16448BMLZ integrates a triaxial gyroscope and triaxial accelerometer (no magnetometer) and provides both SPI and UART interfaces. The ADIS16448BMLZ also offers a wider gyroscope dynamic range of ±2000°/s versus ±350°/s for the ADIS16405BMLZ.
Are the ADIS16405BMLZ and ADIS16448BMLZ pin-compatible and mechanically interchangeable?
Both devices are housed in the same 23 mm × 23 mm × 23 mm module with a 24-pin connector interface, so the mechanical footprint and connector are common. However, pin functions and signal assignments differ between the two models, so they are not directly pin-for-pin interchangeable. The PCB layout and connector wiring must be verified against each device's datasheet before substitution.
Which device includes a magnetometer?
The ADIS16405BMLZ includes a triaxial magnetometer in addition to its triaxial gyroscope and triaxial accelerometer. The ADIS16448BMLZ does not include a magnetometer; it provides only the triaxial gyroscope and triaxial accelerometer.
What are the gyroscope dynamic ranges of the two IMUs?
The ADIS16405BMLZ gyroscope has a dynamic range of ±350°/s. The ADIS16448BMLZ gyroscope has a dynamic range of ±2000°/s, making it better suited to higher-rate angular motion applications.
What digital interfaces do the ADIS16405BMLZ and ADIS16448BMLZ support?
The ADIS16405BMLZ provides a SPI interface. The ADIS16448BMLZ provides both SPI and UART interfaces, giving additional flexibility in system integration.
Do both devices operate from the same supply voltage?
Both the ADIS16405BMLZ and the ADIS16448BMLZ operate from a single 3.0 V to 3.6 V supply. Designers should still confirm the exact supply and decoupling requirements in each device's datasheet.
Can the ADIS16448BMLZ be used as a drop-in replacement for the ADIS16405BMLZ?
No. Although the package and connector are the same, the ADIS16448BMLZ lacks the magnetometer, has a different gyroscope dynamic range, and uses different pin signal assignments and interface options. A direct drop-in replacement is not possible without validating the hardware and firmware against the ADIS16448BMLZ datasheet.
