LiDAR ICs with 2x higher bandwidth for faster self-driving cars
Maxim Integrated Products has introduced what it says are the industry's fastest and smallest light detection and ranging (LiDAR) ICs.

Compared to the closest competitive solution, says the company, the MAX40026 high-speed comparator and the MAX40660/MAX40661 high-bandwidth transimpedance amplifiers 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.

"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," says 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."

Key advantages of the devices are offered as the following:

  • Small Solution Size: The MAX40026 TDFN package size of 4 mm 2 and the MAX40660/MAX40661 TDFN package size of 9 mm 2 provide the industry's smallest overall solution size.
  • Industry's Highest Precision: Maxim Integrated's TIAs support 128 channels with the industry's highest 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.

The MAX40026ATA/VY+T is available for $4.09; the MAX40660 is available for $3.95 (1000-up, FOB USA); and the MAX40661 is available for $3.74 (1000-up, FOB USA). The MAX40026EVKIT# evaluation kit is available for $71.40; the MAX40660EVKIT# evaluation kit is available for $102.90; and the MAX40661EVKIT# evaluation kit is available for $102.90.
