Product Overview

The Allegro A1324, A1325, and A1326 are low-noise, linear Hall-effect sensor ICs designed for high-accuracy applications such as displacement, angular position, and current measurement. These temperature-stable devices offer a voltage output proportional to the applied magnetic field, with a quiescent output voltage of 50% of the supply voltage. Available in miniature surface mount (SOT23W) and ultra-mini through-hole (SIP) packages, they feature factory-programmed sensitivities of 5.0 mV/G, 3.125 mV/G, and 2.5 mV/G respectively. Ideal for automotive and industrial applications requiring operation across an extended temperature range (40C to 150C), they integrate a Hall element, temperature-compensating circuitry, a high-gain amplifier, a clamped output stage, and a dynamic offset cancellation technique for enhanced reliability and accuracy.
