Product Description
Product Overview
The A3213 and A3214 are ultra-sensitive, pole-independent Hall-effect switches with a latched digital output. Designed for low-power, battery-operated devices such as cell phones and palmtop computers, they offer significant power savings through a unique clocking scheme. These devices are ideal for replacing reed switches due to their superior reliability, ease of manufacturing, and elimination of signal conditioning. Chopper stabilization ensures improved stability by reducing offset voltage caused by overmolding, temperature, and thermal stress.
