Linear Hall-effect Sensors
Datasheet
SDC49E
General Description
Features
The SDC49E 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
