Allegro MicroSystems A1182
The A118X is a two-wire, unipolar, Hall-effect switch family designed for use in high-temperature applications. This device uses a patented high frequency chopper-stabilization technique on Allegro's new DABIC5 BiCMOS wafer fabrication process to achieve magnetic stability and to eliminate offset inherent in single-element devices and from harshapplication environments. The A118X FAMILY of devices incorporates a programmability function to allow for external trimming of the operate point.- Max Operating Temp : 200°C
- Min Operating Temp : -65°C
