MAX4389EXT/V+T

Video Amps And Modules Overview

The MAX4389EXT/V+T is a single-channel, unity-gain stable voltage-feedback operational amplifier from Analog Devices. It operates on single supplies of 4.5V to 11V or dual supplies of ±2.25V to ±5.5V. Key electrical specifications 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, low differential gain/phase errors, and a dedicated disable pin that reduces current consumption to 450μA while placing the output in a high-impedance state.

Video Amps And Modules Procurement Notes

Verify the specific suffix '/V' indicates automotive qualification status as defined by the manufacturer's ordering guide. Confirm the 'T' suffix corresponds to tape and reel packaging. Ensure the component meets RoHS compliance requirements before integration into final assemblies.

Video Amps And Modules Selection Notes

Select this part for applications requiring high-speed signal processing in compact form factors. The disable feature is critical for power management in multiplexer configurations. Consider the 85MHz bandwidth and low distortion metrics when designing for video or RF signal paths where signal integrity is paramount.

Video Amps And Modules Part Context

This component belongs to the MAX4389/MAX4390/MAX4392–MAX4396 family of ultra-small, low-cost op amps. The family shares common electrical characteristics but varies in channel count and disable functionality. The MAX4389 specifically denotes the single-channel variant within this series.

Video Amps And Modules Replacement Considerations

Direct replacements within the same family include the MAX4389EUT+T (SOT23 package) or other variants sharing the EXT/V+T designation if package compatibility allows. Verify pinout and thermal characteristics match the existing design constraints.

Video Amps And Modules FAQ

What is the input common-mode voltage range?

The input common-mode voltage range extends to the negative power-supply rail (VEE) and up to VCC minus 2.25V.

How does the disable function affect the output?

When disabled, the output impedance increases to approximately 95kΩ, placing the amplifier in a high-impedance state suitable for switching applications.

Is the MAX4389 unity-gain stable?

Yes, the MAX4389 is internally compensated and guaranteed to be stable at a unity gain configuration.
