MAX3861ETG+T

Overview

The MAX3861ETG+T is a limiting amplifier and post-amplifier IC designed for optical network applications. It operates with a supply voltage range of 3 V to 3.6 V and draws a typical operating current of 94 mA. The device supports data rates up to 2.7 Gbps and features auto gain control functionality. It is housed in a 24-lead TQFN package (4x4 mm) with an exposed pad, suitable for surface mount installation. The component functions within a temperature range of -40°C to +85°C.

Feature Summary

• Integrates auto gain control for signal conditioning
• Designed as a post-amplifier for optical networks
• Supports high-speed data transmission up to 2.7 Gbps

Applications

• Optical network systems
• Fiber optic communication receivers
• Signal processing in optical transceivers

Procurement Notes

Verify component authenticity through authorized distributors or direct manufacturer channels due to discontinued status. Confirm RoHS compliance and lead-free packaging specifications against the official datasheet. Check for obsolescence notices or last-time buy availability from Analog Devices. Ensure the specific suffix matches the required tape-and-reel configuration for automated assembly processes.

Selection Notes

Select this component for designs requiring a dedicated limiting amplifier with integrated gain control in a compact surface-mount package. Evaluate power consumption requirements against the 94 mA typical current draw. Ensure the system interface is compatible with CML or LVDS signaling levels typically supported by this family. Consider thermal management needs given the small TQFN footprint and power dissipation characteristics.

Part Context

This part belongs to the Maxim Integrated optical interconnect portfolio, specifically targeting high-speed fiber optic receiver stages. It complements other laser drivers and transimpedance amplifiers in complete optical module solutions. The TQFN-24 package is common across several Maxim high-speed analog ICs for dense PCB layouts.

Replacement Considerations
