Lidar brings Analog Devices, First Sensor together
Analog Devices Inc. (Norwood, Mass.) has announced it is collaborating with First Sensor AG (Berlin, Germany) on the lidar signal chain for unmanned automotive, aerial and underwater vehicles in transportation, smart agriculture, industrial manufacturing and other industries.

Analog Devices is a maker of trans-impedance amplifiers (TIAs). Recent developments include multi-channel TIAs specifically designed to convert wide dynamic range photocurrent into a low-impedance voltage signal.

First Sensor has more than 25 years of experience manufacturing avalanche photodiodes (APDs), which are highly sensitive detector arrays that convert light into photocurrent. Optimizing the interconnection between the APDs and TIAs influences the noise floor and bandwidth achieved. Improvements in these two parameters translates into lidar systems that can detect objects at longer range and with higher precision.

First Sensor and Analog Devices will each offer a common evaluation board with which system manufacturers can test the combined solution.

"The first step in our working together is to optimize ADI’s industry leading transimpedance amplifiers (TIAs) with First Sensor’s avalanche photodiodes (APDs) so we can offer our customers more powerful and efficient lidar solutions, and better support the mass commercial launch of LIDAR systems into the autonomous transportation market," said Stewart Sellars, general manager of lidar at ADI.

First Sensor is going through the process of being acquired by TE Connectivity and folded into that company's sensor business.
