Product Information

Name:  MMC3416PJ

The MMC3416PJ is an ultra-small complete 3-axis magnetic sensor with on-chip signal processing and an integrated I2C bus. The device can be connected directly to a microprocessor, eliminating the need for A/D converters or timing resources. It can operate from a single 1.8 V supply. The IC can measure magnetic fields within the full-scale range of ±16 Gauss, with 0.5 mG/LSB resolution and 1.5 mG rms noise, enabling heading accuracies of less than 1 degree in electronic compass applications.

An on-demand SET/RESET function provides for the elimination of error due to a Null Field output change with temperature. In addition, it clears the sensors of any residual magnetic polarization resulting from exposure to strong external magnets. The on demand SET/RESET function can be performed for each measurement or periodically as the specific application requires providing the flexibility to maximize performance while minimizing power consumption.

The MMC3416xPJ is packaged in a low profile LGA package (1.6 x 1.6 x 0.6 mm) and has an operating temperature range from −-40 to +85°C.
