A1454 Description
The A1454 linear Hall-effect sensor IC provides a 12-bit digital output word that is proportional to the strength of the magnetic field that is present. Its quiescent output value is at mid-scale, and it es in two different factory-programmed sensitivity ranges: The sensitivity temperature coefficient is also factory-programmed to support either neodymium or ferrite magnets.
A1454 Key Features
- 1 mm thin 8-pin TSSOP package
- Two factory-programmed sensitivity options
- 2 LSB/G (for fields up to ±1000 G)
- 4 LSB/G (±500 G)
- Temperature-stable sensitivity for NdFeB and ferrite magnets
- I2C interface for easy integration, with support for up to 127 unique addresses
- EEPROM stores factory-programmed settings and up to 26 bits of user information (programmable through the I2C interface)
- Micropower sleep mode through I2C mand for minimizing power in battery-operated
