Programmable Digital Gyroscope Sensor
GENERAL DESCRIPTION
The ADIS16260 and ADIS16265 are programmable digital
gyroscopes that combine industry-leading MEMS and signal
processing technology in a single compact package. They provide
accuracy performance that would require full motion calibration
with any other MEMS gyroscope in their class. When power is
applied, the ADIS16260 and ADIS16265 automatically start up
and begin 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 and ADIS16265 provide 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 and ADIS16265 are drop-in replacements for
the ADIS1625x family and come in LGA packages (11.2 mm ×
11.2 mm × 5.5 mm) that meet Pb-free solder reflow profile
requirements, per JEDEC J-STD-020. They have an extended
operating temperature range of −40°C to +105°C.
