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.

●

●

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.
