Product Description
Product Overview
The Allegro A1304 is a linear Hall-effect sensor IC designed for new applications requiring medium accuracy and a small package size. This temperature-stable device offers a voltage output proportional to the applied magnetic field, featuring a quiescent voltage output at 50% of the supply voltage. It integrates a Hall element, offset and sensitivity trim circuitry, a high-gain amplifier, and a proprietary dynamic offset cancellation technique for precise performance. Available in a miniature SOT-23W surface mount package, the A1304 is ideal for space-constrained designs.
