PIN OUT DIAGRAM

Ultra-Sensitive Dual-Channel

Quadrature Hall-Effect Bipolar Switch

The A3425 is a dual-channel, Bipolar switch with two Hall-effect

sensors, each providing a separate digital output for speed and

direction signal processing capability. The Hall elements are both

SOIC

photo-lithographically aligned to better than 1µm.

Maintaining

accurate mechanical location between the two active Hall elements

eliminates the major manufacturing hurdle encountered in fine-pitch

detection applications. The A3425 is a highly sensitive, temperature

stable magnetic sensor ideal for use in ring magnet based speed and

direction systems located in harsh automotive and industrial

environments.

The A3425 monolithic integrated circuit contains two independent Hall

effect switches located 1 mm apart. The digital outputs are out of

phase so that the outputs are in quadrature with the proper ring

magnet design. This allows for easy processing of speed and

direction signals. Extremely low-drift amplifiers guarantee symmetry

between the switches to maintain signal quadrature. The patented

chopper-stabilization technique cancels offsets in each channel

providing stable operation over temperature and voltage. An on-chip

low dropout regulator allows the use of this device over a wide

operating voltage range. Post-assembly factory programming at

Allegro provides for sensitive switch points that are symmetrical

between the two switches.
