I've got an IC device that I can't identify in my school kit. I've lost the parts list, so I can'tlook it up on there. Googling and searching on Mouser and Digikey is a dead end. I think it's a Hall Effect sensor, but without a datasheet I've no clue how to use it. It has three radial leads like a TO-92 package, but it's only about half as big as that. On the curved side it has a stylized "A" with the letters 04E under it. On the flat side, it has the numbers 1032 889N. Any idea what this is, where I can find a data sheet, or at least a clue on who makes it?
