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.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~+125
*TTL and MOS IC are directly drivable by the output
*The life is semipermanent because it employs contact-less parts
*SIP-3 package
