Inertial Sensors: DualShock 4 vs Sixaxis/DS3 accelerometer/gyroscope chips

I was wondering what the difference was between the DS4 & DS3 sensors do I dug up the Datasheets of the Accelerometers & Gyroscope sensors. DS4 has a single IMU made up of a 3 axis digital accelerometer & a 3 axis digital gyroscope. Where DS3 used individual chips, a 3 axis analog accelerometer & a vibration gyro sensor.


Accelerometer g-force measurement range 

DS4 (programmable) ± 2 g, ± 4 g, ± 8 g, ± 16 g 

vs 

DS3 ± 2 g


Gyroscope angular rate measurement range

DS4 (programmable) ± 125°/s, ± 250°/s, ± 500°/s, ± 1000°/s, ± 2000°/s

vs 

DS3 ± 100°/s

Product description The BMI055 is an ultra-small, 6 axis inertial sensor, consisting of: A digital, triaxial 12bit acceleration sensor and a digital, triaxial 16bit, ±2000°/s gyroscope. The BMI055 allows very low-noise measurement of angular rates and accelerations in 3 perpendicular axes and thus senses tilt, motion, shock and vibration in cellular phones, handhelds, computer peripherals, man-machine interfaces, remote and game controllers. With its ultra-small footprint of only 3 mm x 4.5 mm the BMI055 is unique in the class of low-noise inertial measurement units. On top, the BMI055 integrates a multitude of features that facilitate its use especially in the area of motion detection applications, such as device orientation measurement, gaming, HMI and menu browser control. Applications Activity monitoring, step-counting Navigation Vibration measurement, also for active damping Six-dimensional tracking of trajectories Flat detection, tap sensing, menu scrolling Tilt compensation for electronic compass Advanced power management for mobile devices Shock and free-fall detection Image stabilization
