GENERAL DESCRIPTION

The ADIS16080 is a complete angular rate sensor (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 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 for 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 ADIS16080 is available in an 8.2 mm × 8.2 mm × 5.2 mm

16-terminal, peripheral land grid array (LGA) package.
