- Newark Electronics, and Active Electronics, both stock
- the Allegro line (formerly Sprague) of Hall sensors. Some
- are conditioned on-chip, some are conditioned and have a Schmitt
- trigger (digital output only), and some are 'raw'. Contact
- the nearest Allegro office or representative (I have a phone
- number (215) 467-5252, which should work for U.Penn.) for the
- appropriate device data, and buy a few chips and try 'em out.
