General Description
The da311 is a low power high performance capacitive three axes linear accelerometer developed by micromachined technology. These high performance silicon micromachined accelerometers consist of a sensor element and an ASIC packaged in a 3x3x1 mm land grid array (LGA) and it is guaranteed to operate over an extended temperature range from -40掳C to +85掳C. The sensor element is fabricated by single crystal silicon with DRIE process and is protected by hermetically sealed silicon cap from the environment. The device features user selectable full scale of 卤2g/ 卤4g/ 卤8g/ 卤16g measurement range with data output rate from 1Hz to 4KHz with signal condition, temperature compensation, self-test, free fall detection imbedded. The da311 has a self-test mode for user to check the functioning of the sensor and a sleep mode that makes it good for handset power management. Two independent and flexible interrupts greatly simplify the algorithm for various motion status detection. Standard I2C interface is used to communicate with the chip.
