Linear Hall-effect Sensors
Datasheet
SDC3503
General Description
Features
The SDC3503 series linear Hall-effect sensors are small,
Tversatile that are operated by the magnetic field from a
permanent magnet or an electromagnet. The linear
Noutput voltage is set by the supply voltage and varies in
Eproportion to the strength of the magnetic field. The
integrated circuitry features low noise output, which
Mmakes it unnecessary to use external filtering. It also
Uincludes thin film resistors to provide high temperature
DOCstability 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
Rotary encoder

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.
