ADN2841ACP-32

Overview

The ADN2841ACP-32 is a dual-loop laser diode driver from Analog Devices, designed for operation between 50 Mbps and 2.7 Gbps. It utilizes a unique control algorithm to manage average power and extinction ratio after initial factory setup. The device operates on a single 5 V supply and integrates closed-loop control for both power and extinction ratio, minimizing external component count. It features programmable alarms for laser fail and degrade conditions, along with automatic laser shutdown capabilities.

Feature Summary

• Dual-loop control architecture for simultaneous regulation of average optical power and extinction ratio
• Integrated circuitry supporting dual monitor photodiode functionality for DWDM wavelength stabilization
• Built-in diagnostic features including laser fail, laser degrade alarms, and automatic laser shutdown

Applications

• DWDM dual MPD wavelength fixing systems
• SONET OC-1/3/12/48 transmission equipment
• SDH STM-1/4/16 network interfaces
• Fibre Channel applications
• Gigabit Ethernet implementations

Procurement Notes

Verify the specific package variant during procurement, as the ADN2841 series includes both 48-lead and 32-lead LFCSP options with differing functionality levels. Confirm that the selected part matches the required pinout and feature set for your design. Check current availability status as supply may be restricted or subject to factory special order requirements. Ensure compatibility with your system's thermal and electrical specifications before finalizing orders.

Selection Notes

Select this component when designing systems requiring precise dual-loop control of laser diodes at data rates up to 2.7 Gbps. The 32-lead LFCSP package offers reduced functionality compared to the 48-lead version; verify if dual MPD support is necessary for your application. This driver is suitable for applications demanding low external component counts and integrated alarm monitoring for laser health management.

Part Context

The ADN2841 belongs to Analog Devices' family of high-performance laser diode drivers. While the 48-lead LFCSP variant provides full feature sets including dual MPD support, the ACP-32 suffix indicates the 32-lead package which typically offers reduced functionality. Both variants share the core dual-loop control algorithm and high-speed operation capabilities, catering to various optical communication standards.
