March 14, 2014 - Saelig releases IST8303 single-chip 3-axis digital magnetometer sensor, housed in a small form factor (1.6 x 1.6 x 1.0mm) 12-pin BGA package, making it ideal for high-volume surface-mount portable products. The IST8303 is an integrated chip containing 3-axis magnetic sensors with an ASIC controller.
The IST8303 outputs 14/16-bit data over a wide magnetic field range (±1600uT) in a fast-mode 400kHz I2C digital output. Since the host processor does not need to continuously read data from the sensor, the FIFO's "wake up only as needed" operation allows consistent system-power savings. Functioning on 1.8V with a standby current of less than 10uA, very long battery life can be achieved in many portable applications. The IST8303 has three operation modes: stand-by, single measurement - followed by standby, and continuous measurement, where the sensors are measured periodically at a preset frequency.
An interrupt function is employed to detect the occurrence of extraordinary external magnetic fields: when the measured output value exceeds 16 Gauss, the INT register is enabled. The output register contains X, Y, Z axis measurement data stored as two's complement data. Designed in 0.18um technology, the IST8303 features anti-offset and anti-temperature, eliminating errors caused by temperature and factory mismatch. The built-in temperature sensor (-20degC to +85degC) allows for calibration-free designs unaffected by external interference: auto zero-drift eliminates errors from external magnetic sources.
No more wrong tags on mobile phone and tablet images! Hardly bigger than a large grain of salt, the IST8303 is suited to a wide range of portable motion-sensing products such as consumer electronics, digital compasses, GPS/pedestrian navigation, augmented reality applications, magnetometer products, etc.
