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,

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.
