Compared to the closest competitive solution, the MAX40026 high-speed comparator and the MAX40660/MAX40661 high-bandwidth transimpedance amplifiers enable 15 km/h (10 mph) faster autonomous driving at highway speeds by providing more than 2 times the bandwidth and accommodating 32 additional channels (128 vs. 96) to a LiDAR module within the same module size.
With autonomous automotive systems evolving from 56 km/h (35 mph) to 104 km/h (65 mph) and beyond, LiDAR sensors are playing an increasingly important role in vehicle sensor fusion due to their ability to provide accurate object distance measurements. Offering more than double the bandwidth and the capacity to accommodate 33 percent more channels within the same LiDAR module size compared to the closest competitor, the MAX40660/MAX40661 transimpedance amplifiers (TIAs) provide optical receiver designers with higher-resolution images that enable faster autonomous driving systems. The system size of the MAX40026 high-speed comparator plus the MAX40660/1 TIAs is 5 mm² smaller than the closest competitive solution, allowing developers to fit significantly more channels onto space-constrained vehicle platforms. These integrated circuits meet the stringent safety requirements of the automotive industry with AEC-Q100 rating, enhanced electrostatic discharge (ESD) performance and failure modes, effects and diagnostic analysis (FMEDA) to support ISO 26262 certification at the system level.
Key advantages
Small solution size: The MAX40026's 4 mm² TDFN package size and the MAX40660/1's 9 mm² TDFN package size provide the industry's smallest overall solution size.
Industry-leading accuracy: Maxim's TIAs support 128 channels with the industry's highest bandwidth of 490MHz for the MAX40660 and a referred input noise density of 2.1pA/√Hz to support higher-precision distance measurements in LiDAR applications; in addition, the low propagation delay dispersion of the MAX40026 (10 picoseconds) contributes to accurate detection of both stationary and moving objects.
Low power consumption: MAX40660 / 1 reduces current consumption by more than 80 percent in low power mode.
