The A3211 and A3212 are ultrasensitive, pole-independent Hall-effect switches with latched digital output, designed for low-power, battery-operated applications. They feature chopper stabilization for improved stability and can be easily integrated into designs, replacing reed switches with superior reliability. These devices are ideal for portable electronics such as cellular phones, pagers, and palmtop computers.
