MAX4031EEUD+

Video Amps And Modules Overview

The MAX4031EEUD+ is a triple, unity-gain stable operational amplifier manufactured by Analog Devices Inc./Maxim Integrated. It operates from a single 5V supply with a quiescent current of 12mA per amplifier. Key electrical parameters include a 144MHz small-signal bandwidth, 115V/µs slew rate, and 80dB open-loop gain. The device features rail-to-rail outputs capable of driving 150Ω loads and provides ±15kV ESD protection on input and output pins. Each amplifier includes an individual shutdown control pin, reducing current to 0.1µA when disabled. It is specified over the -40°C to +85°C temperature range.

Video Amps And Modules Procurement Notes

Verify the specific package type matches the design requirements, as the EEUD suffix indicates a 14-pin TSSOP package. Confirm that the extended temperature range (-40°C to +85°C) aligns with the operating environment. Ensure that the power supply bypassing and layout guidelines regarding parasitic capacitance are followed to maintain stability and performance characteristics defined in the datasheet.

Video Amps And Modules Selection Notes

Select this component when a triple amplifier configuration is required alongside high-speed signal integrity and robust ESD tolerance. The inclusion of individual shutdown controls makes it suitable for battery-powered portable devices where power management is critical. Verify that the load conditions do not exceed the capacitive loading limits without isolation resistors to prevent oscillation.

Video Amps And Modules Part Context

This part belongs to the MAX4030E/MAX4031E family of low-cost, high-speed operational amplifiers. While the dual-channel MAX4030E lacks shutdown capabilities, the MAX4031E adds independent shutdown pins for each channel. Both share identical speed and ESD protection specifications, differing primarily in channel count and power management features.

Video Amps And Modules Replacement Considerations

The MAX4030E serves as a functional substitute if only two channels are needed and shutdown control is unnecessary. Other members of the MAX4030E/MAX4031E family may be considered based on package preference, such as SOIC or µMAX variants, provided pin compatibility and thermal dissipation requirements are met.

Video Amps And Modules FAQ

How does the MAX4031EEUD+ handle capacitive loads?

The device can drive up to 200pF of capacitive load without sustained oscillation. For larger capacitive loads, an isolation resistor should be placed between the output and the load to maintain stability.

What is the input common-mode voltage range?

The input common-mode voltage extends from ground (0V) to within 2.25V of the positive supply voltage (VCC).

Does the MAX4031EEUD+ support differential video signals?

Yes, the device exhibits low differential gain error (0.2%) and differential phase error (0.2°), making it suitable for preserving signal integrity in video applications.
