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.
