The Honeywell HMC5983 is a temperature compensated three-axis integrated circuit magnetometer. This surface-mount,multi-chip module is designed for low-field magnetic sensing for applications such asautomotive and personal navigation, vehicle detection, and pointing.The HMC5983 includes our state-of-the-art, high-resolution HMC118X seriesmagnetoresistive sensors plus an ASIC containing amplification, automatic degaussingstrap drivers, offset cancellation, and a 12-bit ADC that enables 1° to 2° compass headingaccuracy. The I²C or SPI serial bus allows for easy interface. The HMC5983 is a3.0x3.0x0.9mm surface mount 16-pin leadless chip carrier (LCC).The HMC5983 utilizes Honeywell’s Anisotropic Magnetoresistive (AMR) technology that provides advantages over othermagnetic sensor technologies. Honeywell’s anisotropic, directional sensors excel in linearity, low hysteresis, null outputand scale factor stability over temperature, and with very low cross-axis sensitivity. These sensors’ solid-stateconstruction is designed to measure both the direction and the magnitude of magnetic fields, from milli-gauss to 8 gauss.Honeywell’s Magnetic Sensors are among the most sensitive and reliable low-field sensors in the industry
