SensorDynamics’ new SD746 combo inertial sensors are available from Gleichmann Electronics. The 6 x 6 x 1.2 mm3 inertial sensors perform three axes calibration for acceleration, angular rate and execute a broad angular rate measurement with ±2048°/s and acceleration at ±8 g.
The utmost offset error experienced at ambient temperature in the gyroscope signal is ±5°/s and is ±0.1g for the accelerometer signal. The device shows a room temperature error at ±2% for both the gyroscope and acceleration signals. Apart from all these functional characteristics, the SD746 is provided with a unique power-off mode, for switching off the power consumption, where the SPI connection shows great impedance and constant working in the self-test mode.
This micromechanical combo sensor is available in a compressed QFN40 enclosure and works on a voltage in the range of 2.55 V to 3.6 V with a working thermal range in the order of -40°C to +85°C. It exhibits 6.5 mA power consumption in the normal mode.
The SD746 combo sensor’s reduced power consumption and compact package is advantageous in battery-activated consumer applications, hi-tech industrial systems and in control applications.
