Replacement verdict
Compatible functional replacement candidate
The ADIS16405BMLZ is a higher-grade functional upgrade to the ADIS16365BMLZ, sharing the same SPI interface, 23 mm × 23 mm module footprint, and 3.15 V to 3.6 V supply rail while adding a magnetometer triad and improved gyroscope and accelerometer performance. Both are six-degree-of-freedom inertial sensor modules from the same Analog Devices iSensor family, so the ADIS16405BMLZ can serve as a drop-in functional replacement where the extended sensing capability and tighter bias stability are acceptable, subject to validation of the magnetometer integration and calibration coefficients in the target application.

Key electrical and mechanical differences between the two devices
| Parameter | ADIS16365BMLZ | ADIS16405BMLZ | Why it matters |
|---|---|---|---|
| Gyroscope Dynamic Range | ±300°/sec | ±300°/sec | Defines the maximum angular rate the gyroscope can measure before saturation; matching ranges support similar motion-sensing applications. |
| Accelerometer Dynamic Range | ±18 g | ±18 g | Sets the maximum acceleration measurable; identical ranges ensure comparable shock and tilt sensing capability. |
| Magnetometer | Not included | Tri-axis magnetometer included | The magnetometer enables heading/compass reference; its absence in one part means it cannot provide absolute orientation without external aiding. |
| Gyroscope In-Run Bias Stability | 0.015°/sec | 0.007°/sec | Lower bias stability yields better long-term attitude accuracy; the tighter spec affects navigation-grade performance. |
| Gyroscope Angle Random Walk | 0.05°/√hr | 0.044°/√hr | Represents short-term noise; lower ARW improves integration accuracy over time for attitude estimation. |
| Accelerometer In-Run Bias Stability | 0.1 mg | 0.07 mg | Affects tilt and velocity accuracy; lower bias stability improves long-term accelerometer-based measurements. |
| Temperature Sensor Range | −40°C to +85°C | −40°C to +85°C | On-chip temperature sensing supports bias compensation; matching ranges ensure equivalent thermal compensation capability. |
| Supply Voltage | 4.75 V to 5.25 V | 4.75 V to 5.25 V | Determines power compatibility; identical supply requirements allow drop-in electrical substitution. |
| Operating Temperature Range | −40°C to +105°C | −40°C to +105°C | Defines environmental limits; matching ranges ensure equivalent operation in harsh conditions. |
| Package / Interface | Module, SPI interface | Module, SPI interface | Physical and communication compatibility determines whether the part can be substituted on an existing board. |

Frequently asked questions
What are the key differences between the ADIS16365BMLZ and the ADIS16405BMLZ?
The ADIS16365BMLZ is a six-degree-of-freedom inertial sensor that integrates a triaxial gyroscope and a triaxial accelerometer. The ADIS16405BMLZ adds a triaxial magnetometer to the same gyroscope and accelerometer combination, providing nine degrees of freedom. Both are members of Analog Devices' iSensor family and use the same SPI interface and 23 mm × 23 mm × 23 mm module package, but the ADIS16405BMLZ includes magnetic sensing capability that the ADIS16365BMLZ does not.
Are the ADIS16365BMLZ and ADIS16405BMLZ pin-compatible and mechanically interchangeable?
Yes. Both devices are offered in the same 23 mm × 23 mm × 23 mm module with a 24-pin connector interface and share the same SPI communication interface, supply voltage range, and mounting footprint per Analog Devices documentation. However, because the ADIS16405BMLZ includes a magnetometer, the register map and output data content differ, so firmware must be validated before exchanging one device for the other in an existing design.
What are the gyroscope specifications of the ADIS16365BMLZ and ADIS16405BMLZ?
Both devices use the same triaxial gyroscope core with a selectable full-scale range of ±75°/s, ±150°/s, or ±300°/s and 14-bit output resolution. Analog Devices specifies a gyroscope sensitivity of 0.05°/s/LSB at the ±75°/s setting and 0.2°/s/LSB at the ±300°/s setting for both parts. The in-run bias stability and noise performance are specified identically for the two modules because they share the same gyroscope signal chain.
What accelerometer range and resolution do these modules provide?
Both the ADIS16365BMLZ and ADIS16405BMLZ integrate a triaxial accelerometer with a selectable full-scale range of ±18 g and 14-bit output resolution, giving a sensitivity of approximately 3.33 mg/LSB per Analog Devices datasheet specifications. The accelerometer signal chain is common to both modules.
Does the ADIS16405BMLZ magnetometer have specifications the ADIS16365BMLZ lacks?
Yes. The ADIS16405BMLZ integrates a triaxial magnetometer with a ±2.5 gauss measurement range and 14-bit resolution, providing a sensitivity of approximately 0.5 milligauss/LSB. The ADIS16365BMLZ has no magnetometer and therefore no magnetic field measurement outputs or magnetometer-related registers.
What supply voltage and interface do the ADIS16365BMLZ and ADIS16405BMLZ require?
Both modules operate from a single 5 V supply (4.75 V to 5.25 V) and communicate over a 4-wire SPI interface supporting clock rates up to 2 MHz. Each also provides a programmable interrupt output and an auxiliary 12-bit ADC/DAC interface, per Analog Devices datasheet documentation for the iSensor product line.
Which applications favor the ADIS16405BMLZ over the ADIS16365BMLZ?
The ADIS16405BMLZ is preferred where heading or magnetic field information is required in addition to motion sensing, such as attitude and heading reference systems, platform stabilization with heading feedback, and navigation aids that benefit from magnetometer-aided yaw correction. The ADIS16365BMLZ is appropriate for applications needing only gyroscope and accelerometer data, such as tilt sensing, vibration monitoring, and motion control without heading requirements.
Are the ADIS16365BMLZ and ADIS16405BMLZ rated for the same operating temperature range?
Yes. Both modules are specified by Analog Devices for operation over the −40°C to +105°C industrial temperature range, and both are housed in the same module construction with identical environmental ratings as documented in their respective datasheets.
