Description
●The A 3211 and A3212 integrated circuits are ultra-sensitive, pole in de pen dent Hall-effect switches with latched digital output. These sensors are es pe cial ly suited for operation in battery-operated, hand-held equip ment such as cellular and cordless tele phones, pagers, and palmtop com put ers. A 2.5 volt to 3.5 volt operation and a unique clocking scheme reduce the average op er at ing power requirements to less than 15 μW with a 2.75 volt supply.
