ROHM’s Noise-Tolerant Comparators Serve Automotive Systems

November 1, 2019 Alix Paultre


ROHM unveiled BA8290xYxxx-C-Series ground-sense comparators, offering high tolerance against EMI, useful for sensor applications in automotive systems. The EMARMOUR-based devices have superior noise tolerance when used as comparators to determine the threshold value of sensor output signals, ensuring an output voltage fluctuation within ±1% across the entire noise frequency band per the ISO11452-2 standard. 

Key features include:

  • Groundbreaking noise tolerance to limit output voltage fluctuation to within ±1%.
  • Decreases the number of noise suppression components
  • Meets AEC-Q100
  • Reduces both current consumption (0.6mA vs 0.8mA) and offset voltage (±5mV vs ±7mV) compared to conventional products.
