HALL - EFFECT FOR

HIGH-TEMPERATURE

OPERATION

DESCRIPTION

SK1812 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, contactless switches, and the

like.

FEATURES

* Wide supply voltage range of 2.5V to 20V

* Wide temperature operation range of -20

~+125

℃℃

* Alternating magnetic field operation

* TTL and MOS IC are directly drivable by the output

* The life is semipermanent because it employs contactless parts

* SIP-3 and SOT-23 package

APPLICATIONS

* Speed sensor

* Position sensor

* Rotation sensor

* Contact-less sensor

* Motor control
