STK8312

STK8312 Digital Output 3-axis MEMS Accelerometer Preliminary Datasheet Version - 0.9.9 2012/12/13 STK8312 REV 0.9.9 1. OVERVIEW Description The STK8312 is a ±1.5g/±6g/±16g, 3-axis linear accelerometer, with digital output (I2C). 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 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 x 0.85mm QFN package and it is guaranteed to operate over an extended temperature range from -40 °C to +85 °C. Feature Low Voltage Operation: – Analog Voltage: 2.4 V – 3.6 V – Digital Voltage: 1.7V – 3.6V ±1.5g/±6g/±16g dynamically selectable full-scale I2C digital output interface and 1 interrupt pin 6/8 bit data output 10000 g high shock survivability 3mm x 3mm x 0.85mm QFN Package Configurable Samples per second from 3.125 to 400 samples a second.
