OH495A/OH496B Linear Hall IC

Datasheet Download

The OH490 series products are the high precision linear circuit, and the full voltage range (Rail-to-Rail) output of the product is more effective for the accurate measurement. The output voltage is set by the supply voltage and varies in proportion to the strength of the magnetic field. It can be applied to the measurement of the movement, distance, position sensor, and so on. It is also suitable for the use of harsh environments or severe pollution.

Transfer Characteristics (VCC=5V)

When there is no outside magnetic field (B=0GS), the quiescent output voltage is one-half the supply voltage in general. If a south magnetic pole approaches to the front face (the side with marking ID) of the Hall effect sensor, the circuit will drive the output voltage higher. Contrary, a north magnetic pole will drive the output voltage lower. The variations of voltage level up or down are symmetrical.
