A1230 Dual Channel Quadrature Hall Effect Bipolar Switch, Allegro Microsystems

The Allegro Microsystems A1230 is a dual-channel, bipolar switch with two Hall-effect sensing elements. Each element provides a separate digital output for speed and direction signal processing.

The Hall elements are aligned with an accuracy greater than 1 μm. This accuracy makes it ideal for use in ring magnet based, speed and direction systems located in harsh automotive and industrial environments.

The A1230 contains two independent Hall-effect bipolar switches located 1 mm apart. The digital outputs are out of phase so the outputs are in quadrature when interfaced with the proper ring magnet design. Low-drift amplifiers guarantee symmetry between the switches.

The Allegro high-frequency chopper-stabilisation cancels offsets in each channel providing stable operation over the full specified temperature and voltage ranges.

The A1230 is available in a plastic 8-pin SOIC surface mount package and a plastic 4-pin SIP.
