ICM-20789 Datasheet | TDK Corporation

7-Axis, High Performance Integrated 6-Axis Inertial and Barometric Pressure Sensor GENERAL DESCRIPTION The 7-Axis ICM-20789 is an integrated 6-axis inertial device that bines a 3-axis gyroscope, 3-axis accelerometer, and an ultra-low noise MEMS capacitive pressure sensor in a 24pin LGA package. This unique 7-Axis device offers performance of discrete ponents in a single small footprint for tracking rotational and linear motion as well as pressure differences with an accuracy of ±1 Pa, an accuracy enabling altitude measurement differentials as small as 8.5 cm. The pressure sensor’s MEMS capacitive architecture provides the industry’s lowest noise at the lowest power, high sensor throughput, and temperature coefficient offset of ±0.5 Pa/°C. The pressure sensor’s bination of high accuracy elevation measurements, low power, and temperature stability plemented by the motion tracking 6-axis inertial sensor in a small footprint, make it ideal for a wide range of motion tracking applications. The embedded 6-axis Motion Tracking device bines a 3axis gyroscope, 3-axis accelerometer, and a Digital Motion Processor™ (DMP). An available large 4 k B 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 ICM-20789 has 16-bit ADC for the 6-axis inertial sensor and 24-bit ADC for the pressure Sensor, programmable digital filters, two temperature sensors - one each in 6-axis Inertial and Pressure sensor. The device Features an operating voltage of 1.8V. munication port includes I2C at 400 k Hz (6-axis and Pressure) and 8 MHz SPI (6-axis only). The package is 4x4x1.365 mm 24-pin to minimize board area requirements.
