AK2570 : 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 compensation voltage from the 2channels - 8bits D to A converter to control the Bias- and the Modulation- current for the LD module. The compensation voltage corresponds to the temperature characteristic data of the LD module retained in the on-chip EEPROM and the ambient temperature detected by the on-chip thermo-sensor. AK2570 outputs www.DataSheet4U.com the alarm si.
