Product Overview
The A3213 and A3214 are ultra-sensitive, pole-independent Hall-effect switches with a latched digital output, designed for low-power applications such as battery-operated, hand-held equipment. Their unique clocking scheme significantly reduces average operating power. These devices offer polarity independence, allowing either a north or south pole to activate the output, and are ideal replacements for reed switches due to superior reliability and ease of manufacturing. Chopper stabilization ensures improved stability by reducing residual offset voltage caused by overmolding, temperature dependencies, and thermal stress.
