HIGH SENSITIVITY CMOS HALL-EFFECT LATCH
The AH920 is a Hall-effect latch designed in mixed signal CMOS
technology. It is quite suitable for use in automotive, industrial and
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.
