MAX4389EXT+T

Video Amps And Modules Overview

The MAX4389EXT+T is a single-channel, unity-gain stable voltage-feedback operational amplifier from Analog Devices. It operates on a single 4.5V to 11V supply or dual ±2.25V to ±5.5V supplies. 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 the negative rail, and low differential gain/phase errors. It is housed in a compact 6-pin SC70 package with an operating temperature range of -40°C to +85°C.

Video Amps And Modules Procurement Notes

Verify the specific ordering suffix EXT+T corresponds to the 6-pin SC70 package and tape-and-reel delivery format. Confirm that the lead-free/RoHS-compliant status aligns with project requirements. Ensure the selected component matches the required thermal resistance characteristics for the intended PCB layout.

Video Amps And Modules Selection Notes

Select this part when high-speed signal processing is required within a minimal footprint. The rail-to-rail output swing maximizes dynamic range in low-voltage single-supply systems. Consider the 5.5mA quiescent current if power efficiency is a primary design constraint compared to higher-performance alternatives.

Video Amps And Modules Part Context

This component belongs to the MAX4389/MAX4390/MAX4392–MAX4396 family of ultra-small, low-cost, high-speed op amps. While sharing core electrical specifications like bandwidth and slew rate, the family differentiates by channel count (single, dual, triple, quad) and the inclusion of disable capabilities in specific variants like the MAX4389.

Video Amps And Modules Replacement Considerations

Direct replacements within the same family include the MAX4390EXT+T, which shares the single-channel configuration and SC70 package but lacks the disable pin functionality.

Video Amps And Modules FAQ

Does the MAX4389EXT+T feature a disable mode?

Yes, the MAX4389 includes a disable function that places the amplifier in a low-power state with high-output impedance when the DISABLE pin is active.

What is the input common-mode voltage range?

The input common-mode voltage range extends to the negative power-supply rail (VEE), allowing operation down to ground in single-supply applications.
