Wireless and inertial semiconductor equipments manufacturer, SensorDynamics has expanded its gyroscope portfolio by introducing two MEMS gyroscopes named SD740 and SD742.
The SD740 is a three-axis QFN40-packaged sensor with a volume of 6x6x1.8 mm3, while SD742 is a two axis QFN40-packaged sensor with a volume of 6x6x1.8 mm3. They are available with digital interfaces such as SPI and I2C and with analog interface having two or three outputs. The calibration range of the sensors is up to ±4096°/s. Both the sensors are plant standardized and offset with temperature to reduce temperature fluctuation and error.
The SD740 and SD742 are created to function in a temperature range of -40°C to +85°C and a voltage range of 2.6V to 3.3V. The sensors are compensated for error up to 10°/s at ambient temperature. However, offset error for sensitivity at ambient temperature and temperature fluctuation of sensitivity is a maximum of 5%.
The sensors digital interfaces SPI and I2C can offer a calibration range of ±1024°/s that can be custom-made up to ±4096°/s. The calibrated values are updated internally at a rate of no less than 10 kHz. The pattern of ratio metric analog outputs varies between ±64, ±128, ±256 or ±512°/s. The unique power-off mode in the sensors does not allow power to be consumed. The high impedance of SPI interface of the sensors allows them to be fixed permanently with the bus
The SD740 and SD742 can be used in process control and instrumentation as well as medtech solutions including navigation and robotic control.
