MAX4144EEE+T

Overview

The MAX4144EEE+T is a high-speed, low-distortion differential line receiver manufactured by Analog Devices Inc./Maxim Integrated. It utilizes a three op-amp instrumentation amplifier architecture with fully symmetrical differential inputs and a single-ended output. The device operates from ±5V power supplies (±4.5V to ±5.5V) and features an internally set closed-loop gain of +2V/V. Key electrical parameters include a -3dB bandwidth of 130MHz, a slew rate of 1000V/µs, and a common-mode rejection ratio of 70dB at 10MHz. It provides an output voltage swing of ±3.7V into a 150Ω load and includes shutdown functionality.

Feature Summary

• Three op-amp instrumentation amplifier architecture for high common-mode rejection
• Internally fixed closed-loop gain of +2V/V
• High-speed performance with 130MHz bandwidth and 1000V/µs slew rate
• Low distortion characteristics suitable for video and RF applications

Applications

• Differential to Single-Ended Conversion
• Twisted-Pair to Coaxial Converter
• High-Speed Instrumentation Amplifier
• Medical Instrumentation

Procurement Notes

Verify the specific suffix 'EEE' corresponds to the 16-pin QSOP package and the '+T' indicates tape-and-reel packaging when sourcing. Confirm that the component is sourced from authorized distributors to ensure authenticity. Check for RoHS compliance status as indicated in official documentation. Ensure the supply voltage requirements match the ±5V specification before integration.

Selection Notes

Select this component when a fixed +2V/V gain is required for differential signal reception. It is appropriate for systems operating on dual ±5V supplies. Consider the 130MHz bandwidth and 1000V/µs slew rate for high-frequency signal integrity. Evaluate the 16-pin QSOP package constraints against available PCB space. Compare against MAX4145 or MAX4146 if variable external gain settings are needed instead of a fixed internal configuration.

Part Context

The MAX4144EEE+T belongs to the MAX4144/MAX4145/MAX4146 family of high-speed differential line receivers. While the MAX4145 and MAX4146 offer externally programmable gains, the MAX4144 provides a fixed +2V/V gain. This family shares a similar three op-amp instrumentation amplifier architecture and is designed for balanced, high-speed data transmission systems requiring excellent common-mode rejection.

Replacement Considerations

The MAX4144ESD is a pin-compatible alternative in a 14-pin SO package. For variable gain requirements, consider the MAX4145EEE+T (+1V/V to +10V/V) or MAX4146EEE+T (+10V/V to +100V/V). Verify package dimensions and pinout compatibility before substitution.
