YAS529
MS-3C
Magnetic field Sensor
„ Overview
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.
„ 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.
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
(GPO) Pin
Others.

Note)
Connecting AIZ to VDD is recommended when used by connecting a biaxial inclination sensor.
When the inclination sensor is not used, connecting AIX, AIY, and AIZ to VSS is recommended.
No Schmitt circuit is used for SCL and SDA input pins.
