GENERAL DESCRIPTION
The ADIS16100 is a complete angular rate sensor (gyroscope)
that uses the Analog Devices 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 normal to the top surface of the
package (see Figure 19). 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 to the user to input analog signals for
digitization. An additional output pin provides a precision
voltage reference. Two digital self-test inputs electro-
mechanically excite the sensor to test operation of the
sensor and the signal conditioning circuits.
The ADIS16100 is available in an 8.2 mm 脳 8.2 mm 脳 5.2 mm,
16-terminal, peripheral land grid array (LGA) package.
