The A1366 is a low-noise, high-precision linear Hall-effect sensor IC with factory-programmed sensitivity and quiescent output voltage, designed for accurate current sensing in automotive applications. It features a 4-pin SIP package with a 1 mm case thickness and operates across an ambient temperature range of -40°C to 150°C. The device offers a 120 kHz bandwidth, ratiometric output, and built-in open-circuit detection on the ground pin. AEC-Q100 qualified, it includes proprietary temperature compensation technology to maintain ±1% typical accuracy over temperature. The A1366LKTTN-2-T variant has a factory-programmed sensitivity of 2.5 mV/G.
The A1366 offers precise and stable magnetic field sensing with factory-programmed sensitivity and offset, advanced temperature compensation, and high bandwidth (120kHz) for simplified design.
