Analog Devices Inc. DC2900A Demo Circuit for the LTC6561 is a 16-channel analog LiDAR receiver chain featuring the LTC6561 transimpedance amplifier. This transimpedance amplifier offers 74kΩ transimpedance gain and 30µA linear input current range. The LTC6561 amplifier's fast overload recovery that makes it well suited for LiDAR receivers. The DC2900A features FirstSensor's 16-channel 400nm to 1100nm wavelength sensitive Avalanche Photodiode (APD) array sensor. This sensor feeds four LTC6561s for current to voltage conversion and amplification. The DC2900A AC-coupled output is intended to demonstrate time-domain measurements into 50Ω systems.
