YAS525B

YAS525B MS-1C Magnetic field Sensor „ 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.
