A1326LUA-T

The A1326LUA-T is a Linear Hall Effect Sensor IC with analog output. New applications for linear output hall-effect devices, such as displacement, angular position, current measurement, require high accuracy in conjunction with small package size. The Allegro A1326 linear hall-effect sensor IC designed specifically to achieve both goals. These ratiometric hall effect sensor ICs provide a voltage output that is proportional to the applied magnetic field. They feature a quiescent voltage output of 50% of the supply voltage. The A1326 feature factory programmed sensitivities of 5.0, 3.125 and 2.5mV/G, respectively. Each BiCMOS monolithic circuit integrates a hall element, temperature-compensating circuitry to reduce the intrinsic sensitivity drift of the hall element, a small-signal high-gain amplifier, a clamped low-impedance output stage and a proprietary dynamic offset cancellation technique.

• Temperature-stable quiescent output voltage and sensitivity
• Output voltage proportional to magnetic flux density
• Low-noise output increases accuracy
• Precise recoverability after temperature cycling
• Ratiometric rail-to-rail output
• Immune to mechanical stress
• Solid-state reliability
