A1454
3V Hall Effect Linear Sensor with I2C Output
FEATURES AND BENEFITS
1 mm thin (TSSOP-08) package 2 factory programmed sensitivity options: 2 LSB/G (for
fields up to ±1000 G) and 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
16 bytes of user information (programmable through the I2C interface) Micro-power sleep mode through I2C command for minimizing power in battery-operated applications Precise recoverability after temperature cycling Wide ambient temperature range: –40°C to 125°C 12-bit ADC with 10-bit ENOB (Effective Number of Bits)
Package: 8-Pin TSSOP (suffix LE)
Not to scale
DESCRIPTION
TheA1454 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 comes in 2 different factory programmed sensitivity ranges: 2LSB/G & 4LSB/G. The sensitivity temperature coefficient is also factory programmed to support either Neodymium or Ferrite magnets. The A1454 incorporates an I2C interface for easy integration into a wide variety of applications. 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 programm...
