Allegro MicroSystems, LLC introduces a brand new linear, Hall-effect sensor IC created specifically for applications that need medium accuracy in a really small package. Allegro’s A1304 is really a factory trimmed one-time programmable (OTP-ROM) 3.3 V linear Hall-effect sensor integrated circuit that eliminates the necessity for customers to program these devices to make up for temperature effects on sensor performance. This brand new device may be specifically made both for consumer and industrial markets, and therefore supports a commercial temperature selection of -40 - 85°C.

Allegro’s A1304 includes a typical programmable sensitivity a higher level of 4 mV/G ±6%. Sensitivity and QVO TC are blind blown (trimmed) on the factory for improved accuracy when compared with other inexpensive linear IC’s from Allegro (A1301/02). A1304 device complements Allegro’s existing OTP-ROM linear Hall-effect manufacturer product line through providing a far more cost-effective solution for non-automotive markets. The A1304 circuit, fabricated within a BiCMOS monolithic process, integrates a Hall element, offset and sensitivity trim circuitry to improve for the variation within the Hall element, a small-signal high-gain amplifier, and a proprietary dynamic offset cancellation technique. This temperature-stable, ratiometric Hall-effect sensor gives a voltage output that is certainly proportional to the applied magnetic field and features a quiescent voltage output of 50% in the supply voltage.

The A1304ELHLX-T sensor IC will come in a 3-pin miniature surface mount SOT-23W style package (LH suffix). The package is lead (Pb) free, with 100 percent matte tin leadframe plating. It costs $0.47 in sums of 1,000.
