STK8313

STK8313 Digital Output 3-axis MEMS Accelerometer Preliminary Datasheet Version - 0.9.7 2012/12/13 STK8313 REV 0.9.7 1. OVERVIEW Description The STK8313 is a ±2g/±4g/±8g/±16g, 3-axis linear accelerometer, with I2C digital output. It is a very low power, low profile capacitive MEMS sensor featuring, compensation for 0g offset and gain errors, and conversion to 12-bit digital values at a user configurable samples per second. The self-test capability allows the user to check the functioning of the sensor in the final application. The device can be arranged for sensor data changes, orientation, tap/double tap, and free fall functions through two interrupt pins. The STK8313 is available in a small 3mm x 3mm x 0.85mm QFN package and it is guaranteed to operate over an extended temperature range from -40 °C to +85 °C.
