Linear Hall-effect Sensors

General Description

SDC49E

Features

The SDC49E series linear Hall-effect sensors are small,

versatile that are operated by the magnetic field from a

permanent magnet or an electromagnet. The linear

output voltage is set by the supply voltage and varies in

proportion to the strength of the magnetic field. The

integrated circuitry features low noise output, which

makes it unnecessary to use external filtering. It also

includes thin film resistors to provide high temperature

stability and accuracy.



Extremely sensitive Low dissipation

Low-noise output virtually eliminates the need for

filtering



Flat response up to 23 kHz

Wide operating voltage range: 2.3V~6.5V.

Responds to either positive or negative gauss

Excellent temperature characteristics

Applications



Motor control

Current sensing

Position sensing

Operation Theory

The output null voltage (B=0GS) is nominally one-half the supply voltage. A south magnetic pole, presented to the

branded face of the Hall-effect sensors will drive the output higher than the null voltage level. A north magnetic pole will

drive the output below the null level.
