3-axis hall-sensor magnetic compass ASIC for consumer applications

This magnetic compass ASIC  measures the earth magnetic field through an on-chip Hall sensor (Z) and 2 flipcore sensors (X – Y). The ASIC exhibits a state-of-the-art combination of accuracy, low power consumption and low area/cost. The ASIC in integrated in popular smartphones.

FEATURES:

  • 3 signal condition chains of over 12 bit overall accuracy
  • Low power consumption with programmable accuracies
  • RMS noise of less than 0.5uTrms for less than 1mA
  • SPI, I2C and data processing on-board
  • Wide supply range 1.6 to 3.6V
  • Extremely small area
  • -40 to 85°C
  • 0.18um CMOS technology
