Applications of A3212ELHLT-T
The A3211 and A3212 integrated circuits are ultrasensitive, pole independent Hall-effect switches with latched digital output.
These devices are especially suited for operation in batteryoperated, hand-held equipment such as cellular and cordless telephones, pagers, and palmtop computers.
A 2.5 to 3.5 V operation and a unique clocking scheme reduce the average operating power requirements to less than 15 μW with a 2.75 V supply
