Product Specification
| Voltage - Supply | 4.5V~5.5V | Description | SIP-4 Linear, Compass (ICs) RoHS |

The Allegro A1366 is a factory-programmable linear Hall-effect current sensor IC designed for high accuracy and resolution in current sensing applications. It features proprietary linearly interpolated temperature compensation technology for virtually flat sensitivity and offset across its operating temperature range. This device is ideal for HEV inverters, DC-to-DC converters, and electric power steering (EPS) systems. The A1366 offers a ratiometric voltage output proportional to the applied magnetic field, with factory-programmed sensitivity and quiescent voltage for accuracy of less than 1% typical over temperature. It incorporates a low-noise amplifier, a low-impedance output stage, and a dynamic offset cancellation technique for industry-leading sensing resolution at a 120 kHz bandwidth. Built-in broken ground wire detection enhances reliability in automotive applications.
