Yaw Rate Gyroscope with SPI
ADIS16060
GENERAL DESCRIPTION
The ADIS16060 is a yaw rate gyroscope with an integrated
serial peripheral interface (SPI). It features an externally
selectable bandwidth response and scalable dynamic range.
The SPI port provides access to the rate sensor, an internal
emperature sensor, and two external analog signals (using
t
internal ADC). The digital data available at the SPI port is
proportional to the angular rate about the axis that is normal
to the top surface of the package.
An additional output pin provides a precision voltage reference.
digital self-test function electromechanically excites the sensor
A
to test the operation of the sensor and the signal-conditioning
circuits.
The ADIS16060 is available in an 8.2 mm × 8.2 mm × 5.2 mm,
16-
terminal, peripheral land grid array (LGA) package.
