YAS525B Datasheet | YAMAHA

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, pact and low-power electronic pass 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.
