Product Description
Product Overview
The A3213 and A3214 are ultra-sensitive, pole-independent Hall-effect switches with a latched digital output. Designed for battery-operated, hand-held equipment, they offer reduced average operating power through a unique clocking scheme. Their polarity independence and minimal power requirements allow them to replace reed switches, offering superior reliability and ease of manufacturing without the need for signal conditioning. Chopper stabilization ensures improved stability by reducing residual offset voltage.
