Overview
YAS525B is the biaxial geomagnetic sensor IC integrating a high sensitivity biaxial magnetic sensor, a buffer amplifier, an AD converter (ADC), a clock generator, and serial data interface (supports I2C bus) on one chip.
YAS525B 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 a Si wafer with high precision realizes integration with peripheral circuits.
● High sensitive geomagnetic sensor IC is realized by integrating a magnetic sensor and a low noise buffer amplifier.
● 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 measurements.
● Others.
