The MMC328xMA is a complete 3-axis magnetic sensing system with on-chip signal processing and integrated I2C bus, allowing the device to be connected  directly to a microprocessor eliminating the need for A/D  converters or timing resources. It can measure magnetic fields with a full scale range of +/-8 Gauss. 

The  MMC328xMA is packaged in an ultra small low profile BGA package (2.0 x 2.0 x 1.2 mm, including the 0.2mm height solder ball) and has an operating temperature range of -40°C to +85°C. The MMC328xMA provides  an I2C digital output with 400 KHz, fast mode operation.
