AK2570 Feed Forward APC LSI

AK2570 Feed Forward APC LSI

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 t.

Features

vel retained in the on-chip EEPROM can be set to suit for the characteristics of each LD module. FEATURE
• Realizing all APC function on 1 silicon chip
• Controlling the driving current (the Bias- and the Modulation- current) for the LD module * Consisting of the 2channels - 8bits D to A converter and the Op-amp
• EEPROM (Electrically Erasable Programmable Read Only Memory) * The Non-volatile Memory * The memory capacity : Address 9bits × Data 16bits * Retaining the data of the compensation voltage and the trimming data of the T-SENSE offset voltage and the ALM timing for each LD module
• O.
