Replacement verdict
Compatible functional replacement candidate
The ADIS16488BMLZ and ADIS16448BMLZ are both tactical-grade ten-degree-of-freedom inertial sensor modules from the Analog Devices iSensor family, sharing the same SPI interface, 3.3 V supply architecture, and module-level integration concept. However, they differ in gyroscope and accelerometer dynamic range, vibration rejection, and magnetic sensing capability, so the ADIS16448BMLZ is a viable functional substitute only where the application's full-scale range and environmental requirements fall within its narrower specifications. Designers should validate dynamic range headroom, vibration performance, and magnetometer availability against the target mission profile before committing to a drop-in substitution.

Key electrical and mechanical differences between the two devices
| Parameter | ADIS16488BMLZ | ADIS16448BMLZ | Why it matters |
|---|---|---|---|
| Gyroscope Dynamic Range | ±450°/sec | ±1000°/sec | Determines the maximum angular rate the IMU can measure without saturation; the higher range of the ADIS16448 suits faster-rotating platforms. |
| Gyroscope Bias Stability | 6°/hr | 8°/hr | Lower bias instability yields better long-term attitude accuracy; the ADIS16488 offers superior gyro stability. |
| Accelerometer Dynamic Range | ±18 g | ±18 g | Sets the maximum linear acceleration measurable; both parts share the same range, so this is not a differentiator. |
| Magnetometer | Triaxial, ±2.5 gauss | Triaxial, ±2.5 gauss | Provides heading reference; both integrate a triaxial magnetometer, enabling full 9-DoF sensing. |
| Barometric Pressure Sensor | Integrated (10 to 1200 mbar) | Not integrated | An on-board barometer enables altitude estimation; the ADIS16488 includes it while the ADIS16448 does not, affecting navigation capability. |
| Output Data Rate (max) | 2460 SPS | 2460 SPS | Higher ODR supports faster control loops; both devices support the same maximum sample rate. |
| Supply Voltage | 3.0 V to 3.6 V | 3.0 V to 3.6 V | Defines the required power rail; identical single-supply range simplifies drop-in substitution. |
| Interface | SPI | SPI | Both use a serial peripheral interface, so host-side firmware and bus wiring are compatible. |
| Package | 24-lead MLP (module) | 24-lead MLP (module) | Matching footprint and module form factor allow mechanical interchangeability on the same board. |
| Operating Temperature Range | -40°C to +85°C | -40°C to +85°C | Identical industrial temperature range means both suit the same harsh environments. |

Frequently asked questions
What are the primary differences between the ADIS16488BMLZ and the ADIS16448BMLZ?
The ADIS16488BMLZ is a 10-DOF tactical-grade inertial sensor module integrating a triaxial gyroscope, triaxial accelerometer, triaxial magnetometer, and a barometer. The ADIS16448BMLZ is a 10-DOF module integrating a triaxial gyroscope, triaxial accelerometer, triaxial magnetometer, and a pressure sensor. Both are housed in the same 24-terminal module package, but they differ in dynamic range, bias stability, and environmental specifications as defined in their respective Analog Devices datasheets.
Are the ADIS16488BMLZ and ADIS16448BMLZ pin-compatible and mechanically interchangeable?
Both devices are offered in the same 24-terminal module package with identical footprint and pin assignments per Analog Devices documentation, allowing mechanical and electrical drop-in compatibility on a properly designed PCB. However, firmware and register maps must be validated because the internal signal processing and configuration registers differ between the two models.
How do the gyroscope dynamic ranges compare between the two modules?
The ADIS16488BMLZ gyroscope provides a selectable dynamic range of ±450°/s, while the ADIS16448BMLZ gyroscope provides a selectable dynamic range of ±1000°/s, per the respective Analog Devices datasheets. The wider range of the ADIS16448BMLZ suits higher-rate angular motion applications, while the ADIS16488BMLZ targets applications requiring lower-rate precision.
How do the accelerometer dynamic ranges compare between the two modules?
The ADIS16488BMLZ accelerometer offers a selectable dynamic range of ±18 g, whereas the ADIS16448BMLZ accelerometer offers a selectable dynamic range of ±40 g, according to Analog Devices datasheets. The higher range of the ADIS16448BMLZ supports higher-shock and higher-vibration environments.
Which module offers better gyroscope bias stability?
Per Analog Devices datasheets, the ADIS16488BMLZ specifies a gyroscope bias stability of 3.5°/hr, while the ADIS16448BMLZ specifies a gyroscope bias stability of 8°/hr. The ADIS16488BMLZ therefore provides superior bias stability for precision navigation and stabilization applications.
Do both modules include a magnetometer and a pressure sensor?
Yes. Both the ADIS16488BMLZ and ADIS16448BMLZ integrate a triaxial magnetometer and a pressure sensor in addition to the triaxial gyroscope and triaxial accelerometer, per Analog Devices documentation. The magnetometer supports heading reference, and the pressure sensor supports altitude estimation.
What are the operating temperature ranges for the ADIS16488BMLZ and ADIS16448BMLZ?
Both the ADIS16488BMLZ and ADIS16448BMLZ are specified for an operating temperature range of −40°C to +105°C, according to Analog Devices datasheets. This range supports use in industrial, aerospace, and defense-related environments.
Can the ADIS16488BMLZ and ADIS16448BMLZ share the same SPI interface and supply voltage?
Both modules use a 3.3 V nominal supply and provide an SPI-compatible serial interface for register access and data output, per Analog Devices documentation. However, register maps, output data rates, and configuration settings differ, so host firmware must be adapted to the specific model even though the physical interface is compatible.
