MAX4144ESD+

Overview

The MAX4144ESD+ 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 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 (CMR) of 70dB at 10MHz. It is housed in a 14-pin SO package.

Feature Summary

• Three op-amp instrumentation amplifier architecture for high common-mode rejection
• Internally fixed closed-loop gain of +2V/V
• High slew rate and wide bandwidth for high-speed signal processing
• 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
• High-Speed Differential Line Receiver

Procurement Notes

Verify the component authenticity through official manufacturer channels or authorized distributors. Confirm that the part number matches the specific suffix requirements for the 14-pin SO package and temperature range. Ensure compliance with relevant RoHS directives before integration into production systems.

Selection Notes

Select this component when a fixed gain of +2V/V is required for differential signal reception. It is appropriate for applications demanding high bandwidth and low distortion, such as video transmission over twisted-pair cables. Consider the MAX4145 or MAX4146 if variable external gain settings are necessary instead of a fixed internal configuration.

Part Context

This device belongs to the MAX4144/MAX4145/MAX4146 family of high-speed differential line receivers. While the MAX4145 and MAX4146 offer externally adjustable gains ranging from +1V/V to +100V/V, the MAX4144 provides a fixed +2V/V gain. All variants share similar performance characteristics regarding bandwidth and noise, differing primarily in their gain configuration methods.

Replacement Considerations

Direct functional replacements within the same family include the MAX4145ESD+ and MAX4146ESD+, provided that gain adjustments can be accommodated by the circuit design. External gain-setting resistors must be added if substituting with these variants.
