What is it?

The ADIS16260 is a programmable digital gyroscope that com-bines industry-leading MEMS and signal processing technology in a single, compact package. It provides accuracy performance that would require full motion calibration with any other MEMS gyroscope in its class. When power is applied, the ADIS16260 automatically starts up and begins sampling sensor data, without requiring configuration commands from a system processor. An addressable register structure and a common serial peripheral interface (SPI) provide simple access to sensor data and configuration settings. Many digital processor platforms support the SPI with simple firmware-level instructions. The ADIS16260 provides several programmable features for in-system optimization. The sensor bandwidth switch (50 Hz and 330 Hz), Bartlett window FIR filter length, and sample rate settings provide users with controls that enable noise vs. bandwidth optimization. The digital input/output lines offer options for a data ready signal that helps the master processor efficiently manage data coherency; an alarm indicator signal for triggering master processor interrupts; and a general-purpose function for setting and monitoring system-level digital controls/conditions. The ADIS16260 is a drop-in replacement for the ADIS16250 and comes in an LGA package (11.2 mm × 11.2 mm × 5.5 mm) that meets Pb-free solder reflow profile requirements, per JEDEC J STD-020. It has an extended operating temperature range of –40°C to +105°C.
