產(chǎn)品簡介

GMC303是一種低功耗數(shù)字地磁傳感器，用于電子羅盤的應(yīng)用。

詳細(xì)介紹

GMC303 is a low-power digital geomagnetic sensor for consumer e-compass applications. A highly sensitive Hall-effect magnetic sensor is directly integrated with the signal conditioning IC in a monolithic wafer process. The 8-pin wafer level chip scale package (WL-CSP) measures only 1.2×1.2×0.5mm3. This small package size dramatically increases the design flexibility to developers of compact devices. GMC303 can work harmoniously with the 3-axis digital accelerometer like GMEMS’s GMA303 for directional information. The magnetometer detects the terrestrial magnetism to be compensated by the tilt angle determined from the accelerometer for providing precise navigation heading. GMEMS can provide further software and hardware support for such fusion application.

Features：

1.3-axis geomagnetic sensor for consumer e-compass application
2.Built-in 14-bit ADC with sensitivity 0.6µT/LSB
3.Extended dynamic range of ±4914uT gives extra large room for the sensor placement
4.I2C digital interface supporting standard, fast and high-speed mode 5.Operation voltage: +2.5V ~ +3.6V; IO interface voltage: +1.65V ~ +3.6V

Power consumption:

1.Continuous measurement: typical 650uA@10Hz ODR／3.0mA@100HZ ODR
2.Power down current < 1uA
3.Various operation modes including power-down, single and continuous measurement
4.Self-test function with internal magnetic source
5.8-pin WL-CSP package. Footprint: 1.2mm × 1.2mm, height: 0.5mm.
6.RoHS compliance
