Data Sheet
UNIPOLAR HALL-EFFECT SWITCH
AH922
General Description
The AH922 is a unipolar Hall-effect one-chip switch
with digital output, solution for sense magnetic field.
It is designed in mixed signal CMOS and chopper
technology. This IC is quite suitable for use in
automotive, industrial and consumer applications.
The two sensors are suited for operation over
extended temperature ranges.
The AH922 Hall-effect switch is combined with a
voltage regulator, Hall-voltage generator, chopper
small-signal amplifier, Schmitt trigger and
open-drain output.
The AH922 is available in TO-92S-3 and SOT-23-3
packages.
Features
• Wide Operating Voltage Range
