A1421 sensor equivalent, high precision hall effect ac-coupled differential sensor.
* Integrated tracking capacitor
* Used for sensing motion of ring magnet or ferrous targets
* Wide operating temperature range
* Operation with magnetic i.
including automotive transmission and crankshaft speed sensing.
The device package has an operating ambient temperature.
The A1421, A1422, and A1423 are AC-coupled Hall-effect sensor ICs which include monolithic integrated circuits that switch in response to changing differential magnetic fields created by rotating ring magnets or, when coupled with a magnet, by ferrou.
