A1304

Linear Hall-Effect Sensor IC with Analog Output,

Available in a Miniature, Low Profile Surface Mount Package

DESCRIPTION

FEATURES AND BENEFITS

• 3.3 V supply operation

• Allegro factory programmed offset and sensitivity

• Miniature package

• High bandwidth, low noise analog output

• High speed chopping scheme minimizes QVO drift across

operating temperature range

• Temperature-stable quiescent voltage output and

sensitivity

New applications for linear output Hall effect sensors require

mediumaccuracyandsmallerpackagesize.TheAllegroA1304

linear Hall effect sensor IC has been designed specifically to

achievebothgoals.Thistemperature-stabledeviceisavailable

in a miniature surface mount package (SOT23-W).

This ratiometric Hall effect sensor provides a voltage output

that is proportional to the applied magnetic field and features

a quiescent voltage output of 50% of the supply voltage.

• Precise recoverability after temperature cycling

• Wide ambient temperature range: –40°C to 85°C

• Immune to mechanical stress

Each BiCMOS monolithic circuit integrates a Hall element,

offset and sensitivity trim circuitry to correct for the variation

in the Hall element, a small-signal high-gain amplifier, and a

proprietary dynamic offset cancellation technique.

The A1304 sensor IC is available in a 3-pin surface mount

SOT-23W style package (LH suffix). The package is lead (Pb)

free, with 100% matte tin leadframe plating.
