MAX40026/MAX4066x – Compact LiDAR ICs with Higher Bandwidth for Faster Self Driving Cars
Maxim Integrated Products Inc has introduced new Light Detection and Ranging (LiDAR) ICs that can allow the automotive self-driving system designers to enable high-speed autonomous driving. When compared with other similar products, The MAX40026 high-speed comparator and the MAX40660/MAX40661 high bandwidth Transimpedance Amplifiers (TIAs) enable 10mph(15km/h) faster autonomous driving at highway speeds by providing more than higher bandwidth and accommodating 32 additional channels (128 vs. 96) to a LiDAR module within the same module size.
The MAX40026 comes in a 4mm2 TDFN Package and MAX40660/1 comes in a 9mm2 TDFN Package, this is a 5mm2 smaller than the closest competitive solution, which allows developers to fit far more channels into space-constrained vehicle platforms. The MAX40660 supports 128 channels with the industry’s highest bandwidth of 490MHZ and 2.1pA/√Hz input-referred noise density to support higher accuracy distance measurement in LiDAR applications. The low propagation delay dispersion of the MAX40026 (10 picoseconds) contributes to the accurate detection of both fixed and moving objects. MAX40660/1 reduces current consumption by more than 80% in low power mode.
With more than twice the bandwidth and the ability to accommodate 33% more channels within the same LiDAR module size compared to the closest competitor, the MAX40660/MAX40661 TIAs deliver high-resolution images to the optical receiver designers which enable faster autonomous driving systems. Complete technical details can be found in the MAX40660 Datasheet linked at the bottom of this page.
These ICs meet the stringent 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.
