MAX4090EUT+ is listed in the Video Amps And Modules range at ChipApex. The manufacturer field lists Analog Devices Inc./Maxim Integrated. Its product description is IC AMP BUFFER SOT23-6. Review the specifications below when checking this part for your BOM.
The MAX4090EUT+ is a single-supply video buffer operating from 2.7V to 5.5V with a typical quiescent current of 6.5mA and shutdown current of 150nA. It features an input sync-tip clamp, DC-coupled output, and voltage gain of 2 V/V (6dB). The device provides a small-signal bandwidth of 55 MHz and large-signal bandwidth of 45 MHz. Slew rate is 275 V/µs with settling time to 0.1% at 25 ns. Power supply rejection ratio is 80 dB. Operating temperature range is -40°C to +85°C in a 6-pin SOT23 package.
Verify the specific suffix 'EUT+' corresponds to the SOT23-6 package and extended temperature range (-40°C to +85°C) as documented in the ordering information table. Confirm RoHS compliance status via manufacturer documentation. Ensure compatibility with single-supply operation between 2.7V and 5.5V. Check for any recent product change notices or obsolescence announcements from Analog Devices regarding this part number.
Select this component for portable video applications requiring a compact footprint and low power consumption. The integrated sync-tip clamp simplifies AC-coupling requirements by handling signal positioning internally. The low shutdown current makes it suitable for battery-powered devices where power management is critical. Ensure the application load impedance matches the specified 150Ω back-terminated configuration for optimal performance.
The MAX4090 belongs to a family of 3V/5V video buffers designed for driving DC-coupled, 150Ω back-terminated video loads. Variants include different packages such as SC70 and µDFN, and automotive grades with extended temperature ranges up to +125°C. The EUT+ designation specifically identifies the standard commercial grade version housed in the space-saving SOT23-6 surface-mount package.
Direct substitutes within the same package and specification include MAX4090EXT+ (SC70) and MAX4090ELT+ (µDFN), provided pinout compatibility is verified. Automotive variants like MAX4090AAUT+ offer extended temperature ranges but may require thermal consideration.
