MAX3645EEE-T

Overview

The MAX3645EEE-T is a single-channel limiting amplifier manufactured by Analog Devices Inc./Maxim Integrated. It operates within a supply voltage range of +2.97V to +5.5V and supports data rates from 125Mbps to 200Mbps. The device features a gain-bandwidth product of 250MHz, draws 18mA of operating supply current, and dissipates up to 540mW of power. It is housed in a 16-lead QSOP package with an SMD/SMT installation style and functions across a temperature range of -40°C to +85°C.

Feature Summary

• Provides high-speed signal limiting for optical receiver front-end applications
• Integrates a single channel with wide dynamic range capability
• Designed for low noise performance with minimal input offset voltage

Applications

• Optical communication systems requiring limiting amplification
• Fiber optic transceivers operating at 125Mbps to 200Mbps
• High-speed serial data recovery circuits

Procurement Notes

Verify the specific suffix 'T' against official datasheets to confirm tape-and-reel packaging versus tube variants. Confirm availability status as distribution channels may list limited stock or obsolete status. Ensure the QSOP-16 package matches design requirements before procurement.

Selection Notes

Select this component when a single-channel limiting amplifier is required for optical interfaces. Verify that the 250MHz gain-bandwidth product meets the bandwidth needs of the target data rate. Check compatibility with the available supply voltage range between 2.97V and 5.5V.
