Overview
YAS526C is the Triaxial Geomagnetic Sensor IC integrating high sensitivity triaxial Magnetic Sensors, A/D inputs for inclination sensors, temperature sensor for inclination sensor temperature characteristics correction, Buffer Amplifiers, A/D Converters, Clock Generators, and Serial Data Interfaces (supports I2C) on a multi-chip package.
YAS526C allows you to make up a high sensitive, compact and low-power electronic compass in a portable GPS system or a mobile phone.

FEATUREs
● A manufacturing process that makes magnetic sensor on Si wafer with high precision realizes integration with peripheral circuits on one chip.
● High sensitive geomagnetic sensor IC is realized by integrating magnetic sensors and low noise amplifiers.
● Three A/D input pins for inclination sensor
● High noise immunity is improved by digitizing output from geomagnetic sensor IC.
