OH921HighSensitivityHallLatch

OH921 High Sensitivity Hall Latch IC

Built-in Pull-up Resistor

 

General Description

Part No: OH921 

Temperature Range: -40 to 125°C   

Package:1000 Pcs/Bag

 

The OH921 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 causedby 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.
