Description

The AK09919C is  a 3-axis electronic compass IC, also known as a magnetometer, with high-sensitibity Hall sensor technology.
The AK09919C has a built-in hihg-sensitibity magnetic sensor that detects geomagnetism, a sensor drive circuit, a signal amplifier, and a processing calculation logic, and outputs the magnitude of the magnetic field in each of X, Y, Z axes as digital value.
The AK09919C is ideal for application such as smartphone and smart watch that provide azimuth information for pedestrian navigation functions.
