Maxim Integrated introduces the industry’s smallest LiDAR ICs
Maxim Integrated Products, Inc. says it has introduced the industry's fastest and smallest Light Detection and Ranging (LiDAR) ICs. Compared to the closest competitive solution, the MAX40026 high-speed comparator and the MAX40660/MAX40661 high-bandwidth transimpedance amplifiers (TIAs) enable 10 mph (15 km/h) faster autonomous driving at highway speeds by providing more than 2x higher bandwidth and accommodating 32 additional channels (128 vs. 96) to a LiDAR module within the same module size.
The system size of the MAX40026 high-speed comparator plus the TIAs is reportedly 5 mm2 smaller than the closest competitive solution, which allows developers to fit more channels into space-constrained vehicle platforms. These ICs meet the safety requirements of the automotive industry with AEC-Q100 qualification, enhanced electrostatic discharge (ESD) performance and failure modes, effects, and diagnostic analysis (FMEDA) to support ISO 26262 certification at the system level.
According to the company, key advantages include:
- Small solution size: The MAX40026 TDFN package size is 4 mm2 and the MAX40660/MAX40661 TDFN package size is 9 mm2.
- High precision: The TIAs support 128 channels with a bandwidth of 490 MHz for MAX40660 and 2.1 pA/√Hz input-referred noise density to support higher accuracy distance measurement in LiDAR applications; in addition, low propagation delay dispersion of the MAX40026 (10 picoseconds) contributes to accurate detection of both fixed and moving objects.
- Low power: MAX40660/MAX40661 reduces current consumption more than 80% in low power mode.
"Automotive engineers need elements that support greater precision, lower power, and smaller solution size in order to add next-generation LiDAR capabilities to cars rolling off the assembly line," said Veronique Rozan, Executive Director of Business Management, Core Automotive and Special Projects at Maxim Integrated. "Advancements in LiDAR-based solutions will support greater driver awareness and safety from next-generation automotive navigation systems."
