Preliminary Datasheet

LINEAR HALL EFFECT IC

AH49F

General Description

The AH49F 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

proportion to the strength of the magnetic field.

The integrated circuitry features low noise output,

which makes it unnecessary to use external filtering

components. It also includes precision resistors to

provide increased temperature stability and accuracy.

The operating temperature range of these linear Hall

sensors is -40°C to 105°C, appropriate for

commercial, consumer, and industrial environments.

The AH49F is available in standard TO-92S and

SOT-23-3 packages.
