Product Overview
The SC4723 is an ultra-low power, high-speed linear Hall effect sensor designed for applications requiring proportional response to magnetic flux density. It features a single-pole magnetic response, consuming only 0.8mA of current (ICC) at 3.3V, making it ideal for battery-powered devices. With a fast response time of less than 5s and a detection bandwidth of 250kHz, it offers high-speed, high-precision sensing. The sensor operates over a wide temperature range of -40 to 105 and a supply voltage range of 2.5V to 5.5V. Typical applications include motor positioning, analog magnetic keyboards, magnetic tag identification, and game controllers.
