ADN2830 - Continuous Wave Laser Average Power Controller

General Description

The ADN2830 provides closed-loop control of the average optical power of a continuous wave (CW) laser diode (LD) after initial factory setup.

The control loop adjusts the laser IBIAS to maintain a constant back facet monitor photodiode (MPD) current and thus a constant laser optical power.

Key Features

  • Bias Current Range 4 mA to 200 mA Monitor Photodiode Current 50 ␮A to 1200 ␮ A Closed-Loop Control of Average Power Laser FAIL and Laser.
