MAX4445ESE+

Video Amps And Modules Overview

The MAX4445ESE+ is a differential-to-single-ended line receiver manufactured by Analog Devices Inc./Maxim Integrated. It operates from ±4.5V to ±5.5V supplies and features a small-signal bandwidth of 550MHz with a slew rate up to 3800V/µs. The device provides an input offset voltage of 65mV maximum, quiescent current of 5.5mA maximum, and output drive capability of 120mA. It includes a low-power enable mode reducing current to 3.5mA and accepts gains of +2V/V or greater via an external resistor.

Video Amps And Modules Feature Summary

• Utilizes a three op amp instrumentation amplifier architecture for symmetrical differential inputs and single-ended output
• Features a low-power enable mode that reduces supply current consumption significantly when disabled
• Capable of driving heavy loads such as 100Ω resistors to high voltage swings due to high output current drive

Video Amps And Modules Applications

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

Video Amps And Modules Procurement Notes

Verify the specific ordering suffix corresponds to the desired package and temperature range. Confirm RoHS compliance status through official manufacturer documentation prior to procurement. Ensure the component matches the exact part number specifications for your design requirements.

Video Amps And Modules Selection Notes

Select this component for applications requiring ultra-high-speed signal processing with minimal distortion. Consider the MAX4444 variant if a fixed internal gain of +2V/V is sufficient, whereas the MAX4445 allows for adjustable gain settings using an external resistor. Evaluate power constraints against the enabled and disabled current profiles.

Video Amps And Modules Part Context

This device belongs to the MAX4444/MAX4445 family of ultra-high-speed, low-distortion differential line receivers. These components are designed for video and RF signal-processing applications where maintaining signal integrity at high frequencies is critical. They utilize current-feedback techniques to achieve wide bandwidths while preserving low noise characteristics.

Video Amps And Modules Replacement Considerations

The MAX4444ESE+ serves as a functional substitute within the same family, offering identical performance but with a fixed internal closed-loop gain of +2V/V instead of externally adjustable gain.
