Allegro Microsystems 1-Axis Through Hole Hall Effect Sensor 3 V 3.6 V, Analogue, SIP, 3-Pin

The features of the Allegro A1318 and A1319 make them Ideal for use in automotive and industrial applications requiring high accuracy, and operate across an extended temperature range, –40°C to 150°C linear Hall-effect sensor ICs have been designed specifically to meet these requirements. These temperature-stable devices are available in both surface-mount and through hole packages. The accuracy of each device is enhanced via end-of-line optimisation.

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 A1318 and A1319 sensor ICs are offered in two package styles. The LH is a SOT-23W style, miniature, low profile package for surface-mount applications. The UA is a 3-pin, ultra-mini, single inline package (SIP) for through-hole mounting. Both packages are lead (Pb) free, with 100% matte tin leadframe plating.
