 详细说明：MPU-6500 是全球首例 9 轴运动处理传感器。它集成了 3 轴 MEMS 陀螺仪, 3 轴 MEMS加速度计,以及一个可扩展的数字运动处理器 DMP(Digital Motion Processor),可用 I2C 接口连接一个第三方的数字传感器,比如磁力计。 扩展之后就可以通过其 I2C 或 SPI 接口输出一个 9 轴的信号(SPI 接口仅在 MPU-6000 可用)。MPU-60X0 也可以通过其 I2C 接口连接非惯性的数字传感器,比如MPU6500产品说明书 3电气特性 31陀螺仪规格 除非另有说明,否则4.2节的典型工作电路,VDD=1.8V,VDD|o=1.8V,TA=25°C PARAMETER CONDITIONS IN TYP UNITS NOTES GYROSCOPE SENSITIVITY Full-scale Range I FS SEL=O ±250 FS SEL-1 FS SEL=2 ±1000 itivity Scale Factor FS SEL-O LSB/(/s) FS SEL=1 655 LSB/(/s) FS_SEL=2 32.68 333333332 25C ±3 Sensitivity Scale Factor Variation Over 40°Cto+85°G ±4 % Nonlinearity Best fit straight line: 25G Cross-Axis Sensitivity ZERO-RATE OUTPUT亿zRo In itial zRo Tolerance 25°C ZRO Variation Over Temperature ±0.24 o/s/C GYROSCOPE NOISE PERFORMANCE(FS_SEL=D) Total RMS Naise DLPFCFG=2(92Hz) 0.1 °s-rms GYROSCOPE MECHANICAL FREQUENCIES KHz LOW PASS FILTER RESPONSE GYROSCOPE START-UP TIME From Sleep mode OUTPUT DATA RATE Programmable, Nomal(Filtered) 8000 mode Table 1: Gyroscope Specifications 笔记 1源自部件的验证或表征,不保证在生产中。 2在生产中测试过。 3设计保证。 4根据总RMS噪声计算 3/23 MPU6500产品说明书 PARAMETER CONDITIONS MIN TYP MAX UNITS NOTES ACCELEROMETER SENSITIVITY AFS SEL=O AFS SEL=1 Full-Scalc Rangc FS SEL=2 AFS SEL=3 ±16 gggg ADC Ward Length Output in two' s complement format 16 AFS SEL=O 16,384 AFS SEL=1 8.192 Sensitivity Scale Factor sB/g AFS SEL=2 LSB/q 33333332 Initial Tolerance Compcnent-lovel -40°Cto+85° AFS SEL=0 Sensitivity Change vs Temperature ±0026 C 1 Nonlinearity Best Fit Straight Line ±C5 Cross-Axis]Sensitivity ZERO-G OUTPUT %%g Initial Tolerance Companent-level, all axes ±60 40ct+85℃.
