BCD AH920Z3-G1 High sensitivity cmos hall-effect latch Datasheet

Product Brief
HIGH SENSITIVITY CMOS HALL-EFFECT LATCH
Description
AH920
Parametric Table
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.

Benefits
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.
