ADN8820 EDFA and CW Laser Controller

The ADN8820 is a versatile Continuous Wave (CW) and EDFA laser diode driver and controller. It provides a low noise and precise current control for driving a source or pump laser diode. It can be set to operate in one of four controller modes: Constant Current (CC), Constant Laser Power (CLP), Const.
