The TMAG5273 (A2) magnetometer utilizes three independent Hall-effect sensors to measure magnetic field strength along orthogonal axes. Each axis feeds into a high-resolution 12-bit analog-to-digital converter (ADC), providing digital output via a configurable I2C interface. Its integrated CORDIC (COordinate Rotation DIgital Computer) engine performs real-time trigonometric calculations, enabling precise 360° angle measurement for both on-axis and off-axis magnetic sources without external processing.
Designed for reliability in embedded and industrial environments, the module includes a built-in temperature sensor for thermal compensation, reducing sensitivity drift. It supports configurable power modes, including active, wake/sleep, and deep sleep, optimizing energy consumption from 2.3mA active down to 5nA sleep current. The board features 3.3V and 5V logic level compatibility and is pre-assembled with STEMMA QT (JST-SH) connectors for solder-free prototyping and system integration.
