General Description

Features

Preliminary Datasheet

AH49E

The AH49E is a small, versatile linear Hall-effect

device that is operated by the magnetic field from a

permanent magnet or an electromagnet. The output

voltage is set by the supply voltage and varies in pro-

portion 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 precision resistors to provide increased

temperature stability and accuracy. The operating tem-

perature range of these linear Hall sensors is -40oC to

85oC, appropriate for commercial, consumer and

industrial applications.

The AH49E is available in standard TO-92S package.
