A3209 - ULTRA-SENSITIVE HALL-EFFECT SWITCHES

Low Average Power. Internal timing circuitry activates the sensor for 60 µs and deactivates it for the remainder of the period (480 µs for the A3209Ex and 60 ms for the A3210Ex). A short "awake" time allows for stabilization prior to the sensor sampling and data latching on the falling edge of the t.

3209 AND 3210 Package Suffix ‘LH’ Pinning 3 MICROPOWER, ULTRA-SENSITIVE HALL-EFFECT SWITCHES 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 operating power requirements
