ANALOG DEVICES DC2803A

DC2803A demonstration circuit features the LTC®6560 single channel transimpedance amplifier (TIA) with output multiplexing. The LTC6560, which features 74Kohm transimpedance gain and 30µA linear input current range, is ideal for LIDAR receivers using Avalanche Photodiodes (APD). The LTC6560 operates from 5V single supply and consumes only 90mW. Utilizing the LTC6560’s output MUX, multiple LTC6560 devices can be combined to a single output. The LTC6560’s fast overload recovery makes it well suited for LIDAR receivers. The LTC6560’s single-ended output can swing 2VP-P on a 100 ohm load. The DC2803A utilizes a single channel 400nm to 1100nm wavelength sensitive APD sensor feeding an LTC6560 for current to voltage conversion and amplification. The APD is DC coupled to the TIA to facilitate fast output multiplexing. The DC2803A is intended to demonstrate time domain measurements into 50 ohm systems.
