Description

The STK8312 is a ±1.5g/±6g/±16g, 3-axis linear accelerometer, with digital output(I 2 C). It is a very low power, low profile capacitive MEMS sensor featuring, compensation for 0g offset and gain errors, and conversion to 6/8-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 used for sensor data

changes and orientation through an interrupt pin (INT).The STK8312 is available in a small 3mm x 3mm x0.85mm QFN package and it is guaranteed to operate over an extended temperature range from -40 ° C to +85° C.
