MAX4090AAXT+

Video Amps And Modules Overview

The MAX4090AAXT+ is a single-channel video buffer amplifier manufactured by Analog Devices Inc./Maxim Integrated. It operates from a single supply voltage ranging from 2.7V to 5.5V and features an integrated input sync-tip clamp circuit for DC-coupled output applications. The device provides a typical voltage gain of 2 V/V (6dB) and includes a low-power shutdown mode that reduces quiescent current to 150nA. It is housed in a 6-pin SC70 package and is specified for operation over the extended automotive temperature range of -40°C to +125°C.

Video Amps And Modules Procurement Notes

Verify the specific suffix 'A' indicates the automotive temperature grade (-40°C to +125°C) compared to standard industrial grades. Confirm the 'XT' designation corresponds to the SC70 package type. Ensure compatibility with system power rails within the 2.7V to 5.5V operating range before integration.

Video Amps And Modules Selection Notes

Select this component when a high-bandwidth video buffer with built-in signal conditioning is required. The integrated clamp eliminates external components for sync positioning. Consider the SC70 footprint constraints and verify that the 6.5mA active current meets battery life requirements, utilizing the shutdown pin to minimize drain during standby periods.

Video Amps And Modules Part Context

This part belongs to the MAX4090 family of 3V/5V video buffers. The 'A' prefix denotes the extended automotive temperature rating, while 'XX' specifies the SC70 package variant. Other family members include variants with different temperature ranges or package types such as SOT23 and µDFN, offering flexibility for various form factors.

Video Amps And Modules Replacement Considerations

Direct replacements within the same package and temperature grade are limited due to specific pinout and electrical characteristic variations. Verify functional equivalence regarding bandwidth, slew rate, and clamp voltage if substituting with other video buffer ICs.
