AK2570 Overview
AK2570 is the monolithic CMOS LSI has the function of ‘ Feed Forward Automatic Power Control (APC)’ for the Laser Diode (LD) module and maintains the emission intensity of the LD module constant with the high accuracy. For stabilizing the emission intensity of the LD module affected by the ambient temperature, AK2570 feeds the pensation voltage from the 2channels - 8bits D to A converter to control the Bias- and the...
