A1324LUA-T

The A1324LUA-T is an Allegro MicroSystems A1324 low-noise linear Hall-effect sensor IC with a factory-programmed sensitivity of 5.0 mV/G, in a 3-pin ultramini SIP through-hole package. It provides an analog voltage output proportional to the applied magnetic flux density, with a quiescent output at half the supply and a ratiometric rail-to-rail output that tracks the supply voltage, so the reading stays consistent for an ADC that shares the same reference. The device integrates the Hall element, temperature-compensating circuitry, a small-signal high-gain amplifier, a clamped low-impedance output stage and a proprietary dynamic offset cancellation technique on a single die, which gives a low-noise output, a stable offset and precise recoverability after temperature cycling. It operates from a single 4.5 V to 5.5 V supply, has a bandwidth of about 17 kHz, and works over an extended -40 °C to +150 °C temperature range, and it is immune to mechanical stress for solid-state reliability. The 5.0 mV/G sensitivity suits a small magnetic field and a short air gap, such as a precise position or displacement measurement. Typical uses include linear and rotary position sensing, motor commutation, contactless current measurement and proximity detection in automotive and industrial equipment. Every sensor BeiLuo ships is factory-traceable and includes an import declaration, a certificate of origin and a RoHS compliance file. Our FAE team helps you choose the sensitivity and the package and plan the magnetic circuit.
