MAX4144ESD+T

Overview

The MAX4144ESD+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 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 (CMR) of 70dB at 10MHz. It is housed in a 14-pin SO package and supports an operating temperature range of -40°C to +85°C.

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 fast 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

Procurement Notes

Verify the component authenticity by checking the manufacturer marking against the official datasheet specifications. Confirm the package type matches the 14-SO format and ensure the suffix indicates the correct temperature grade. Cross-reference the ordering information section to validate the specific part number variant before finalizing procurement decisions.

Selection Notes

Select this component when a fixed gain of +2V/V is required for differential signal reception. It is appropriate for systems needing high bandwidth and low distortion without external gain-setting resistors. Consider the MAX4145 or MAX4146 if variable gain ranges are necessary instead of a fixed internal configuration.

Part Context

This component belongs to the MAX4144/MAX4145/MAX4146 family of high-speed differential line receivers. While the MAX4145 and MAX4146 offer externally adjustable gain ranges, the MAX4144 provides a fixed gain configuration. All variants share similar architectural benefits, including laser-trimmed matched thin-film resistors for high CMR.

Replacement Considerations

Direct pin-compatible replacements within the same family include the MAX4145ESD+T and MAX4146ESD+T. Note that these alternatives require external resistors for gain setting and have different fixed gain characteristics compared to the MAX4144.
