TDK InvenSense ICM-20789 7軸慣性和大氣壓力傳感器在單個小尺寸外形中設(shè)有各種高性能的分立元件，用于跟蹤旋轉(zhuǎn)和線性運動以及壓差。ICM-20789是一款集成式6軸慣性器件，在24引腳LGA封裝中結(jié)合了3軸陀螺儀、3軸加速度計，以及超低噪聲MEMS電容式壓力傳感器。

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™ (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 – 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.
