The A3209Ex and A3210Ex integrated circuits are ultra-sensitive, pole independent Hall-effect switches with a latched digital output. They are especially suited for operation in battery-operated, hand-held equipment such as cellular and cordless telephones, pagers, and palmtop computers. 2.5 volt to 3.5 volt operation and a unique clocking scheme to reduce the average operat- ing power requirements the A3209Ex to 400, the A3210Ex to 25 ! Except for operating duty cycle and average operating current, the A3209Ex and A3210Ex are identical. NUED PRODUCT By Allegro MicroSystems, Inc.
