GENERAL DESCRIPTION
The ADIS16100 is a gyroscope that uses the Analog Devices,
Inc., surface-micromachining process to make a functionally
complete angular rate sensor with an integrated serial peripheral
interface (SPI).
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 (see Figure 20). A single external resistor can be
used to increase the measurement range. An external capacitor
can be used to lower the bandwidth.
Access to an internal temperature sensor measurement is
provided through the SPI for compensation techniques.
Two pins are available for the user to input analog signals for
digitization. An additional output pin provides a precision
voltage reference. Two digital self-test inputs electromechanically
excite the sensor to test the operation of the sensor and the
signal-conditioning circuits.
The ADIS16100 is available in an 8.2 mm × 8.2 mm × 5.2 mm,
16-terminal, peripheral land grid array (LGA) package.
