Description:
High precision hall effect ac-coupled differential sensor.
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 ferrous targets.
This family of devices also includes an
A1421 Features
