High Precision HMC5843 Digital Compass 3-Axis Magnetoresistive Sensors

High Precision HMC5843 Digital Compass 3-Axis Magnetoresistive Sensors
Descriptions:
- The Honeywell HMC5843 is a surface mount multi-chip module  designed for low field magnetic sensing with a digital interface for applications  such as low cost compassing and  magnetometry. The HMC5843 includes our state of the art 1043 series magneto-resistive sensors plus  Honeywell developed ASIC containing amplification, strap drivers, offset cancellation, 12-bit ADC and an I2C serial bus interface. The HMC5843 is in a 4.0 by 4.0 by 1.3mm  surface mount leadless chip  carrier (LCC). Applications for the HMC5843 include  Consumer Electronics, Auto Navigation Systems, Personal Navigation Devices, and Magnetometers.

- The HMC5843 utilizes Honeywell’s Anisotropic Magnetoresistive (AMR) technology that provides advantages over other magnetic sensor technologies. The sensors feature precision in-axis sensitivity and linearity, solid-state construction with very low cross-axis sensitivity designed to measure both direction and magnitude of Earth’s magnetic fields, from tens of micro-gauss to 6 gauss. Honeywell’s Magnetic Sensors are among the most sensitive and reliable low-field sensors in the industry.
