3 General Description isentek IST830 is a 3-axis digital magnetometer with 3.0x3.0x.0mm 3, 6-pin LGA package. It is an integrated chip with 3-axis magnetic sensors, digital control logic, built-in temperature compensation circuit and self-test function. IST830 provides an I 2 C digital outpu with fast mode up to 400kHz. The highh output dataa rate, ultra-low hysteresis, excellent temperaturee drift and low noise performance feathers make it a perfect candidate for high accuracy applications. Features Single chip 3-axis magnetic sensor 3. 0x3.0x.0mmm 3, 6-pin LGA packagee I 2 C slave, Fast Mode up to 400kHz 4 bits data output W High output data rate of maximum 200Hz Ultra-low hysteresis (<0.%FS) Ultra-low sensitivity temperature drift (±0.06 %/ o K) Ultra-low offset temperature drift (0.024uT/ o K) W Wide dynamic range of ±600uT (x, y-axis) and ±2500uT (z-axis) Wide operating temperature range High precision temperature compensation Built-in self-test function Software and algorithm support available (For tilt compensatio n, cross-axiss compensation and noise suppression) Applications Quadcopter/Dronee Applications Augmented Reality Applications irtual Reality Applications Location Based Services Navigation Applications Industrial Applications Magnetometry IOT devices Heading Gaming IST830 Datasheet, ersion.2 3
