LINEAR INTEGRATED CIRCUIT
HALL-EFFECT SWITCH FOR
HIGH-TEMPERATURE
OPERATION
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°С.This Hall IC is suitable for
application to various kinds of sensors, contact-less switches, and
the like.
FEATURES
* Wide supply voltage range of 2.5V to 20V
* Wide temperature operation range of -20°С~+125°С
* TTL and MOS IC are directly drivable by the output
* The life is semipermanent because it employs contact-less parts
