DESCRIPTION
LINEAR INTEGRATED CIRCUIT
1
SIP-3
The UTC
SK1816A
is a semiconductor integrated circuit utilizing
the Hall effect. It designed 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, such as Speed sensor, Position sensor,
Rotation sensor, Contact-less sensor, and Motor control.
