Replacement verdict
Compatible functional replacement candidate
The ADIS16460AMLZ and ADIS16488BMLZ are both tactical-grade MEMS inertial measurement units from Analog Devices sharing the same SPI interface and 15-pin connector footprint, but they differ substantially in sensor suite, dynamic range, and performance class. The ADIS16460AMLZ is a compact 6-DoF IMU, while the ADIS16488BMLZ integrates a full 10-DoF sensor set including a triaxial magnetometer and barometer. Substitution is feasible only after validating gyroscope and accelerometer range, bias stability, and the additional sensor requirements against the target application.

Key electrical and mechanical differences between the two devices
| Parameter | ADIS16460AMLZ | ADIS16488BMLZ | Why it matters |
|---|---|---|---|
| Number of Axes / Sensor Type | 6-DOF (3-axis gyroscope + 3-axis accelerometer) | 10-DOF (3-axis gyroscope + 3-axis accelerometer + 3-axis magnetometer + barometer) | The ADIS16488BMLZ integrates magnetometer and barometer sensing, providing heading and altitude references that the ADIS16460AMLZ cannot supply, so they are not functionally interchangeable for full navigation solutions. |
| Gyroscope Dynamic Range | ±100°/s | ±450°/s | A wider gyro range allows the ADIS16488BMLZ to measure higher angular rates without saturation, which is critical for high-dynamics platforms. |
| Gyroscope Bias Stability | 6°/hr | 3.5°/hr | Lower bias instability yields better long-term attitude accuracy, giving the ADIS16488BMLZ an advantage in precision navigation applications. |
| Accelerometer Dynamic Range | ±5 g | ±18 g | The higher accelerometer range of the ADIS16488BMLZ supports high-shock and high-acceleration environments that would clip the ADIS16460AMLZ. |
| Accelerometer Bias Stability | 0.1 mg | 0.13 mg | Accelerometer bias stability affects velocity and position drift; the ADIS16460AMLZ offers slightly better accelerometer bias performance. |
| Output Data Rate (ODR) | Up to 2000 SPS | Up to 2460 SPS | Higher output data rate enables faster control-loop updates and better capture of high-frequency motion in the ADIS16488BMLZ. |
| Supply Voltage | 3.0 V to 3.6 V | 3.0 V to 3.6 V | Both devices share the same supply range, simplifying power-supply design when considering substitution. |
| Interface | SPI (serial peripheral interface) | SPI (serial peripheral interface) | A common SPI interface means both parts can connect to the same host controller bus, easing hardware-level replacement. |
| Package / Footprint | Module, 24-lead (approx. 24 mm x 37 mm x 9 mm) | Module, 24-lead (approx. 24 mm x 37 mm x 9 mm) | Matching module footprints allow a drop-in mechanical replacement between the two parts on an existing board design. |
| Operating Temperature Range | -40°C to +85°C | -40°C to +85°C | Identical temperature ratings ensure both parts suit the same industrial and harsh-environment applications. |

Frequently asked questions
What are the primary differences between the ADIS16460AMLZ and the ADIS16488BMLZ?
The ADIS16460AMLZ is a compact tactical-grade inertial measurement unit (IMU) in a 24-lead LGA package (approximately 24 mm × 30 mm × 3.2 mm) that integrates a triaxial gyroscope and triaxial accelerometer. The ADIS16488BMLZ is a higher-performance tactical-grade IMU in a larger 44-lead module package (approximately 44 mm × 47 mm × 14 mm) that adds a triaxial magnetometer and a barometric pressure sensor to the gyroscope and accelerometer set, and provides lower gyroscope bias instability and angle random walk than the ADIS16460.
Do the ADIS16460AMLZ and ADIS16488BMLZ have the same SPI interface and register map?
Both devices use a 4-wire SPI interface for configuration and data readout, but they are not register-compatible. The ADIS16488BMLZ provides additional registers for its magnetometer and barometer channels and a different output data rate and filter configuration structure. Firmware written for one device cannot be reused on the other without modification and revalidation against the respective datasheets.
Which device offers better gyroscope bias instability?
The ADIS16488BMLZ specifies a lower gyroscope bias instability than the ADIS16460AMLZ. Per the Analog Devices datasheets, the ADIS16488BMLZ gyroscope bias instability is typically 0.3 °/hr, while the ADIS16460AMLZ is typically 1.2 °/hr. The ADIS16488BMLZ is therefore the better choice when long-term bias stability is the dominant requirement.
Can the ADIS16460AMLZ be used as a drop-in replacement for the ADIS16488BMLZ?
No. The two devices differ in package footprint, pinout, supply and interface details, sensor complement, and register map. A direct drop-in replacement is not possible; a redesign of the PCB land pattern, power sequencing, and host firmware would be required, followed by full validation against the ADIS16460AMLZ datasheet.
Which device includes a magnetometer and barometric pressure sensor?
Only the ADIS16488BMLZ integrates a triaxial magnetometer and a barometric pressure sensor in addition to the triaxial gyroscope and triaxial accelerometer. The ADIS16460AMLZ provides only the gyroscope and accelerometer channels, so applications requiring heading reference or altitude aiding must use the ADIS16488BMLZ or add external sensors.
How do the supply voltage and power consumption compare?
Both devices operate from a single 3.0 V to 3.6 V supply. The ADIS16460AMLZ draws significantly less power, with a typical operating current on the order of tens of milliamps, while the ADIS16488BMLZ draws a higher current due to its additional sensor channels and larger signal processing. Designers should confirm exact typical and maximum current values from the respective Analog Devices datasheets for thermal and power budgeting.
Which device is better suited to space-constrained or weight-limited designs?
The ADIS16460AMLZ is the better fit for space- and weight-constrained designs. Its LGA package is substantially smaller and lighter than the 44-lead module package of the ADIS16488BMLZ, at the cost of lower gyroscope performance and the absence of magnetometer and barometer channels.
Are both devices rated for the same operating temperature range?
Both the ADIS16460AMLZ and ADIS16488BMLZ are specified for an operating temperature range of −40 °C to +85 °C per their Analog Devices datasheets. Applications outside this range require separate qualification and are not covered by the published specifications.
