HIGH SENSITIVITY CMOS HALL-EFFECT LATCH
AH920
General Description
The AH920 is a Hall-effect latch designed in mixed
signal CMOS technology. It is quite suitable for use
in automotive, industrial and consumer applications.
Superior high-temperature performance is made
possible through dynamic offset cancellation, which
reduces the residual offset voltage normally caused
by device over-molding, temperature dependencies,
and thermal stress. The device integrates a voltage
regulator, Hall-voltage generator, small-signal
amplifier, chopper stabilization, schmitt trigger, and
open-drain output.
An on-board regulator permits operation with supply
voltage from 3.5V to 20V.
The AH920 is available in TO-92S-3 and SOT-23-3
packages, which are optimized for most applications.
