3V Hall-Effect Linear Sensor Delivers I²C Output

3V Hall-Effect Linear Sensor Delivers I²C Output
Allegro MicroSystems Inc.

Sporting an I²C interface and presenting a 12-bit digital output word that is proportional to the strength of the magnetic field that is present, the quiescent output of the A1454 is at mid-scale. It comes in two different factory programmed sensitivity ranges: 2LSB/G and 4LSB/G. Sensitivity temperature coefficient is also factory programmed to support either neodymium or ferrite magnets. The I²C address can either be set by external resistors or programmed via EEPROM, to support up to 127 unique I²C addresses, allowing for multiple ICs on the same bus. It also includes 16 bytes of user programmable EEPROM. The A1454 is priced at $0.85 each/1,000.
