A1454 3V Hall Effect Linear Sensor with I2C Output FEATURES AND BENEFITS DESCRIPTION ? 1 mm thin (TSSOP-08) package The A1454 linear Hall effect sensor IC provides a 12-bit digital ? 2 factory programmed sensitivity options: 2 LSB/G (for output word that is proportional to the strength of the magnetic fields up to ±1000 G) and 4 LSB/G (±500 G) field that is present. Its quiescent output value is at mid-scale, and ? Temperature-stable sensitivity for NdFeB and ferrite it comes in 2 different factory programmed sensitivity ranges: magnets 2LSB/G 4LSB/G. The sensitivity temperature coefficient ? I2C interface for easy integration with support for up to is also factory programmed to support either Neodymium or 127 unique addresses Ferrite magnets. The A1454 incorporates an I2C interface for ? EEPROM stores factory programmed settings and up to easy integration into a wide variety of applications. The I2C 16 bytes of user information (programmable through the address can either be set by external resistors or programmed I2C interface) via EEPROM, to support up to 127 unique I2C addresses, ? Micro-power sleep mode through I2C command for allowing for multiple ICs on the same bus. It also includes 16 minimizing power in battery-operated applications bytes of user programmable EEPROM. ? Precise recoverability after temperature cycling The A1454 I2C interface provides a user-controlled sleep input ? Wide ambient temperature range: –40°C to 125°C command that puts the device in micro-power mode, which ? 12-bit ADC with 10-
