A1325LUA-T

The A1325LUA-T is an Allegro MicroSystems A1325 low-noise linear Hall-effect sensor IC with a factory-programmed sensitivity of 3.125 mV/G, in a 3-pin ultramini SIP through-hole package. It is the middle member of the A1324/5/6 family and 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. The device integrates the Hall element, temperature-compensating circuitry, a high-gain amplifier, a clamped output stage and a 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 range, and it is immune to mechanical stress for solid-state reliability. The 3.125 mV/G sensitivity sits between the 5.0 mV/G A1324 and the 2.5 mV/G A1326, so it suits a medium field and a moderate air gap where the A1324 would saturate but the A1326 would give too little output. Typical uses include position and displacement sensing, angle measurement, motor commutation and contactless current sensing 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.
