The MPU-9250 is the company’s second generation 9-axis MotionTracking device
for smartphones, tablets, wearable sensors, and other consumer markets. The
MPU-9250, delivered in a 3x3x1mm QFN package, is the world’s smallest 9-axis
MotionTracking device and incorporates the latest InvenSense design innovations,
enabling dramatically reduced chip size and power consumption, while at the same
time improving performance and cost. The MPU-9250 MotionTracking device sets a
new benchmark for 9-axis performance with power consumption only 9.3µA and a
size that is 44% smaller than the company’s first-generation device. Gyro noise
performance is 3x better, and compass full scale range is over 4x better than
competitive offerings.
The MPU-9250 is a System in Package (SiP) that combines two chips: the
MPU-6500, which contains a 3-axis gyroscope, a 3-axis accelerometer, and an
onboard Digital Motion ProcessorTM (DMPTM) capable of processing complex
MotionFusion algorithms; and the AK8963, the market leading 3-axis digital
compass. The MPU-9250 supports InvenSense’s market proven 9-axis MotionFusion. A
single design can support the MPU-9250 or MPU-6500, providing customers the
flexibility to support either device in different product skews.
Improvements include supporting the accelerometer low power mode with as
little as 6.4µA of and it provides improved compass data resolution of 16-bits
(0.15 µT per LSB). The full scale measurement range of ±4800µT helps alleviate
compass placement challenges on complex pcb’s.
The MPU-9250 software drivers are fully compliant with Google’s latest
Android 4.1 Jelly Bean release, and support new low-power DMP capabilities that
offload the host processor to reduce power consumption and simplify application
development. The MPU-9250 includes MotionFusion and run-time calibration
firmware that enables consumer electronics manufacturers to commercialize cost
effective motion-based functionality.
General Description The MAX21000 is a low power, low noise, 3-axis angular rate sensor that delivers unprecedented accuracy and sensitivity over temperature and time. It operates with a supply voltage as low as 1.71V for minimum power consumption. It includes a sensing element and an IC interface that provides the measured angular rate to the external world through a digital interface (I 2 C/SPI). The IC has a full scale of ±31.25/±62.50/±125/±250/ ±500/±1k/±2k degrees per second (dps) and measures rates with a finely tunable user-selectable bandwidth. The high ODR and the large BW, the low noise at highest FS, together with the low phase delay, make the IC suitable for both user interface (UI) and optical image stabilization (OIS) applications. The IC is a highly integrated solution available in a com- pact 3mm x 3mm x 0.9mm plastic land grid array (LGA) package...
