SC470X Ultra-Low Power High-Speed Linear Hall Sensor

Product Overview
The SC470X is an ultra-low power, high-speed linear Hall effect sensor designed for applications requiring proportional response to magnetic flux density. With an ultra-low current consumption of 0.7mA at 3.3V and a fast response time of less than 5s, it is ideal for battery-powered devices and high-precision applications. The sensor offers a wide operating voltage range of 2.5V to 5.5V and an extended operating temperature range of -40 to 105. It features temperature-compensated, low-noise output with a detection bandwidth of up to 250kHz, making it suitable for industrial and consumer electronics, motor positioning, magnetic keyboard interfaces, magnetic tag identification, and gaming controllers.
