DESCRIPTION
SK1901 is a semiconductor integrated circuit utilizing the Hall effect.
It has been so designed as to operate in the alternating magnetic
field especially at low supply voltage and operation over extended
temperature ranges to +125℃.This Hall IC is suitable for application
to various kinds of sensors, contact-less switches, and the like.
