ICM-20789 七轴压力传感器

TDK InvenSense ICM-20789 7轴惯性和大气压力传感器在单个小尺寸外形中设有各种高性能的分立元件，用于跟踪旋转和线性运动以及压差。ICM-20789是一款集成式6轴惯性器件，在24引脚LGA封装中结合了3轴陀螺仪、3轴加速度计，以及超低噪声MEMS电容式压力传感器。 The pressure sensor features MEMS capacitive architecture to provide low noise at low power, high sensor throughput, and temperature coefficient offset of ±0.5 Pa/°C. A combination of high accuracy elevation measurements, low power, and temperature stability complemented by the motion tracking 6-axis inertial sensor in a small footprint, is ideal for a wide range of motion tracking applications. The embedded 6-axis MotionTracking device combines a 3-axis gyroscope, 3-axis accelerometer, and a Digital Motion Processor&trade (DMP). A large 4 kB FIFO reduces traffic on the serial bus interface, and power consumption through burst sensor data transmission. The Gyroscope has programmable FSR of ±250 dps, ±500 dps, ±1000 dps and ±2000 dps. The Accelerometer FSR is programmable to ±2g, ±4g, ±8g and ±16g. The ICM-20789 incorporates a 6-axis inertial sensor and 24-bit ADC for the pressure sensor, programmable digital filters, two temperature sensors &ndash one each in the 6-axis inertial and pressure sensor. Features include an operating voltage of 1.8V and the communication port includes I2C at 400kHz (6-axis and pressure) and 8MHz SPI (6-axis only). A 4mm x 4mm x 1.365mm 24-pin package minimizes board area requirements.
