Allegro MicroSystems, LLC introduces a new programmable linear Hall-effect sensor IC designed for applications that require high accuracy and high resolution without compromising bandwidth. Allegro’s A1377 employs segmented, linearly interpolated temperature compensation technology. This improvement greatly reduces the total error of the device across the whole temperature range. As a result, the device is ideally suited for sensing in numerous automotive applications, such as linear and rotary position sensors in actuators and valves.

The A1377 is available in a through-hole, small form factor, single in-line package (SIP) and has a broad range of sensitivity and offset operating bandwidth. The accuracy and flexibility of this device is enhanced with user programmability, via the VCC and output pins, which allows the device to be optimized in the application.

This ratiometric Hall-effect sensor IC provides a voltage output that is proportional to the applied magnetic field. The quiescent voltage output (QVO) is user-adjustable from approximately 5% to 95% of the supply voltage. The device sensitivity is adjustable within the range of 1 to 14 mV/G.

The features of this linear device make it ideal for use in automotive and industrial applications requiring high accuracy, and apply across an extended temperature range, from –40°C
to 150°C. 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.

The A1377 sensor is provided in a 3-pin single in-line package (UC suffix) with bypass capacitors integrated into the package. It is lead (PB) free, with 100% matte-tin leadframe plating.
