SensorDynamics, a producer of single-axis and multi-axis inertial and wireless sensors for the automotive and manufacturing industries, today announced the launch of its new SD742 and SD740 micromechanical gyroscopes. The SD742 adds an XY angular rate and the SD740 an XYZ angular rate device to the firms line of 6x6x1.8 mm3 QFN40-packaged sensors. In addition to having two or three analog outputs, it comes with I²C and SPI digital interfaces, along with a wide measurement range of up to ±4096°/s. These features make for a high degree of flexibility with respect to its applications. Also the SD742 and SD740 are temperature-compensated and factory calibrated to minimize offset error and temperature drift.
The SD742 and SD740 are designed for an operating voltage of 2.6 through 3.3 V and an operating temperature range
of -40 through +85°C. Their maximum offset error is 10°/s at room temperature and 5°/s over the entire operating temperature range, while their sensitivity error at room temperature and temperature drift of sensitivity is maximal 5%,
respectively. Those parameters can be improved by a factor of 2 upon special customer request. The two digital
interfaces provide a full scale standard measurement range of ±1024°/s., which can be customized up to ±4096°/s.
The internal updating of measured values is provided at a high rate of at least 10 kHz. The ratio metric analog outputs
can be configured for ±64, ±128, ±256 or ±512°/s measurement ranges. The SD742 and SD740 devices also feature
a special power-off mode in which no power is consumed, but the SPI interface remains high-impedance so that the
sensor need not be removed from the bus.

rate sensor, or visit www.sensordynamics.cc.
Its low power consumption of approx. 5 mA and small package outline of only 6x6x1.8 mm³ makes the SD742/SD740
suitable for battery-powered applications such as controlling artificial limbs in medicine. For instance it can also be
utilized for sophisticated instrumentation and control purposes in the industry, such as robot control and navigation.
The sensors feature a continuously operating self-test that monitors the functional capability of the two or three
dimensional angular rate sensor element without interrupting measurements.
Availability and price
The 2D gyroscope SD742 is available now and the 3D gyroscope SD740 will be available in December. Samples and
evaluation boards can be ordered from www.sensordynamics.cc. If you wish to receive a competitive quote for series
production, please contact your local SensorDynamics representative.
