DC2900A Demo Circuit for the LTC6561

Analog Devices Inc. DC2900A Demo Circuit for the LTC6561 is a 16-channel analog LiDAR receiver chain featuring the LTC6561 trans-impedance amplifier. This trans-impedance amplifier offers 74kΩ trans-impedance gain and 30µA linear input current. The LTC6561 amplifier's fast overload recovery 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.
