线性霍尔芯片

SDC49E

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.


Features
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
