Build with MMC5603 — Datasheet Specs & AI Design Help

00 — Overview

What the MMC5603 does

The MMC5603NJ is a monolithic 3-axis AMR magnetic sensor featuring on-chip signal processing and digital bus interfaces. It operates with a ±30 Gauss field range, 20-bit resolution, and 2 mG total RMS noise, enabling heading accuracy of ±1º. The device supports a 1.62V to 3.6V single supply and offers a maximum output data rate of 1000 Hz. It includes an integrated SET/RESET function for error elimination and temperature compensation. Typically used in electronic compasses, GPS navigation, and position sensing, the sensor connects directly to microprocessors via I2C or I3C without external A/D converters. Its ultra-small 0.8x0.8x0.4 mm package fits compact designs across commercial and industrial temperature ranges.
