A1454 Overview
Key Specifications
Package: TSSOP
Mount Type: Surface Mount
Pins: 8
Max Voltage (typical range): 3.5 V
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 comes in two different factory-programmed sensitivity ranges: 2 LSB/G and 4 LSB/G.
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 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)
