HIGH SENSITIVITY CMOS HALL-EFFECT LATCH
AH921
General Description
The AH921 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 is directly drivable by the output.
An on-board
regulator permits operation with supply voltage from 3.
5V to...
