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 I
2
C 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 I
2
C 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.
●
