A1266 Overview
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.
Key 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+Y+Z) output
