Magnetic field Sensor
YAS529 is the Triaxial Geomagnetic Sensor IC integrating buffer amplifier, A/D converter, clock generator,
and serial data interface circuit (supports I2C bus) on one chip package.
YAS529 allows you to make up a high sensitive, compact and low-power electronic compass in a portable
GPS system or a mobile phone.
● 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
● High noise immunity is improved by digitizing output from geomagnetic sensor IC.
● External interface supports I2C 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.
● Three A/D input pins for an inclination sensor
● Power-down control of an inclination sensor with a standby pin by the use of the General-Purpose Output
