Unspecified 

MPU-9150 Product Specification

Document Number: PS-MPU-9150A-00

Revision: 4.3

Release Date: 9/18/2013

5 Features

5.1 Gyroscope Features

The triple-axis MEMS gyroscope in the MPU-9150 includes a wide range of features:

 Digital-output X-, Y-, and Z-Axis angular rate sensors (gyroscopes) with a user-programmable full-

scale range of ±250, ±500, ±1000, and ±2000°/sec

 External sync signal connected to the FSYNC pin supports image, video and GPS synchronization

 Integrated 16-bit ADCs enable simultaneous sampling of gyros

 Enhanced bias and sensitivity temperature stability reduces the need for user calibration

 Improved low-frequency noise performance

 Digitally-programmable low-pass filter

 Factory calibrated sensitivity scale factor

 User self-test

5.2 Accelerometer Features

The triple-axis MEMS accelerometer in MPU-9150 includes a wide range of features:

 Digital-output 3-Axis accelerometer with a programmable full scale range of ±2g, ±4g, ±8g and ±16g

 Integrated 16-bit ADCs enable simultaneous sampling of accelerometers while requiring no external

multiplexer

 Orientation detection and signaling

 Tap detection

 User-programmable interrupts

 High-G interrupt

 User self-test

5.3 Magnetometer Features

The triple-axis MEMS magnetometer in MPU-9150 includes a wide range of features:

 3-axis silicon monolithic Hall-effect magnetic sensor with magnetic concentrator

 Wide dynamic measurement range and high resolution with lower current consumption.

 Output data resolution is 13 bit (0.3 µT per LSB)

 Full scale measurement range is ±1200 µT

 Self-test function with internal magnetic source to confirm magnetic sensor operation on end

products

5.4 Additional Features

The MPU-9150 includes the following additional features:

 9-Axis MotionFusion via on-chip Digital Motion Processor (DMP)

 Auxiliary master I2C bus for reading data from external sensors (e.g., pressure sensor)

 Flexible VLOGIC reference voltage supports multiple I2C interface voltages

 Smallest and thinnest package for portable devices: 4x4x1mm LGA

 Minimal cross-axis sensitivity between the accelerometer, gyroscope and magnetometer axes

 1024 byte FIFO buffer reduces power consumption by allowing host processor to read the data in

bursts and then go into a low-power mode as the MPU collects more data

 Digital-output temperature sensor

 User-programmable digital filters for gyroscope, accelerometer, and temp sensor

 10,000 g shock tolerant
