YAS526C
MS-2
Magnetic field Sensor
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 I
2
C) 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.
●
External interface supports I
2
C bus (100kbps/400kbps, slave mode).
●
Geomagnetic sensor with superior high board density and low-power consumption.
●
Automatic power-down control mode is available after geomagnetic measurements.
●
Temperature sensor for inclination sensor temperature characteristics correction
●
