AH920
AH920 is HIGH SENSITIVITY CMOS HALL-EFFECT LATCH manufactured by Diodes Incorporated.
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, Hallvoltage 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.
