Description

Freescale’s MAG3110FCR1 is a small, low-power, digital 3-axis magnetometer that falls under the product category of Hall Effect Digital Sensors. It can be used in conjunction with a 3-axis accelerometer to realize an orientation-independent electronic compass that provides accurate heading information. The device features a standard I2C serial interface output and smart embedded functions. The MAG3110FCR1 measures magnetic fields with an output data rate (ODR) of up to 80 Hz and corresponds to sample intervals that range from 12.5 ms to several seconds. Moreover, it is available in a plastic DFN package and is guaranteed to operate over the extended temperature range of -40°C to +85°C.
