Gleichmann Electronics - Micromechanical 6DoF combo sensor with power-saving wake-up on motion function
Gleichmann Electronics now offers the SD746, a micromechanical six degrees of freedom (6DoF) combo sensor from SensorDynamics. The new SD746 features a power-saving wake-up on motion function where power consumption is drastically reduced by turning off the angular rate sensor and operating the acceleration sensor for motion detection with a low sample rate.
In nThe SD746 comes in a tiny QFN 40 package and offers six degrees of freedom (6DoF) for measurement of angular rate and acceleration along all three axes over a wide measurement range of up to ±2048°/s for angular rate and up to ±8g for acceleration. The temperature-compensated and calibrated measurement values can thereby either be read out via I²C or SPI interface.
The SD746 is designed for an operating voltage of 2.55 V to 3.6 V and an operating temperature range from -40°C to +85°C. The maximum offset error at room temperature is ±5°/s for the angular rate signal and ±0.05g for the acceleration signal. The maximum sensitivity error at room temperature is ±2% for both the angular rate and acceleration signals.
