A1266 - Micropower Ultrasensitive 3D Hall-Effect Switch

Description

The A1266 integrated circuit is an ultrasensitive Hall-effect switch with 3D omnipolar magnetic actuation.

The single silicon chip includes: three Hall plates, multiplexer, smallsignal amplifier, chopper stabilization, Schmitt trigger, and NMOS output transistors.

Features

  • True 3D sensing.
  • Omnipolar operation with either north or south pole.
  • 2.5 to 5.5 V operation.
  • Low supply current.
  • High sensitivity, BOP typically 25 G.
  • Chopper-stabilized offset cancellation.
  • Superior temperature stability.
  • Extremely low switch point drift.
  • Insensitive to physical stress.
  • Solid-state reliability.
  • Choice of output format.
  • Separate X, Y, and Z outputs.
  • Combined (X+.
