AK2571 Overview
The AK2571 is a single-chip solution for WDM Laser Diode Module applications. It integrates both ATC (Auto Temperature Control) and APC (Auto Power Control) functions in a small 64-pin LQFP or bare die package.. The ATC function of the AK2571 detects the LD module temperature via an external thermister and uses the PID algorithm to control the Thermo-Electric Cooler (TEC).
