MAX4393EUB+T

Video Amps And Modules Overview

The MAX4393EUB+T is a dual-channel, unity-gain stable voltage-feedback operational amplifier from the MAX4389/MAX4390/MAX4392–MAX4396 family. It operates on single supplies of 4.5V to 11V or dual supplies of ±2.25V to ±5.5V. Key electrical characteristics include an 85MHz small-signal bandwidth, a 500V/μs slew rate, and a quiescent current of 5.5mA per amplifier. The device features rail-to-rail outputs, input common-mode range extending to VEE, and a low-power disable mode consuming 450μA. It is housed in a 10-pin μMAX package with an operating temperature range of -40°C to +85°C.

Video Amps And Modules Procurement Notes

Verify component authenticity through authorized distribution channels. Confirm that the ordering suffix corresponds to the specific package type and tape-and-reel configuration required for your assembly process. Ensure compliance with RoHS standards indicated by the plus sign in the part number.

Video Amps And Modules Selection Notes

Select this device when high-speed video signal processing requires low distortion and wide bandwidth. The dual-channel configuration with individual disable pins makes it suitable for multiplexer applications. Consider the 10-pin μMAX package for space-constrained designs requiring surface-mount technology.

Video Amps And Modules Part Context

This component belongs to the MAX4389/MAX4390/MAX4392–MAX4396 family of ultra-small, low-cost op amps. The MAX4393 specifically provides two amplifiers with disable functionality, distinguishing it from non-disable variants like the MAX4392. It shares core performance metrics with the broader family while offering channel-specific control.

Video Amps And Modules Replacement Considerations

Direct replacements within the same family include the MAX4392EUA+T (dual, no disable) or MAX4394ESD+T (triple, with disable). Verify pin compatibility and disable logic requirements before substitution.

Video Amps And Modules FAQ

How does the disable function affect the output impedance?

When the DISABLE pin is active (logic low), the amplifier enters a high-impedance state with an output resistance of approximately 95kΩ, suitable for switching applications.

What is the recommended isolation resistor for capacitive loads?

A small isolation resistor, typically between 10Ω and 15Ω, should be placed in series with the output to prevent ringing and oscillation when driving capacitive loads.
