Overview
A1304 Linear Hall-Effect Sensor IC with Analog Output, Available in a Miniature, Low-Profile Surface Mount Package 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 • Precise recoverability after temperature cycling • Wide ambient temperature range: –40°C to 85°C • Immune to mechanical stress Package: 3-Pin Surface Mount SOT23-W (suffix LH) DESCRIPTION New applications for linear output Hall-effect sensors require medium accuracy and smaller package size.
TheAllegroA1304 linear Hall-effect sensor IC has been designed specifically to achieve both goals.
This temperature-stable device is available 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.
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.
