Daisy 7
6DOF Digital MEMS Accelerometer And Giroscope For Fox G20
Features
Digital triple axis accelerometer and digital triple axis gyros
Digital-output X, Y, and Z-Axis ±2g ±4g ±8g dynamically selectable full-scale acceleration
Digital-output X, Y, and Z-Axis angular rate sensors (gyros) on one integrated circuit with a sensitivity of 14.375 LSBs per deg/sec and a full-scale range of ±2000 deg/sec
Fast Mode I2C (400kHz) serial interface
16 bit data output ADCs provide simultaneous sampling of gyros and acceleration while requiring no external multiplexer
Daisy Ready
3 independent programmable interrupt generators for free-fall and motion detection
Sleep to wake-up function
Embedded self-test
10000 g high shock survivability
Enhanced bias and sensitivity temperature stability reduces the need for user calibration
ECOPACK RoHS and Green compliant
Applications
Motion activated functions
Free-fall detection
Intelligent power saving for handheld devices
Appliances and robotics
