MAX4394ESD+

Video Amps And Modules Overview

The MAX4394ESD+T is a triple, high-speed operational amplifier from the MAX4389–MAX4396 family. It operates on single supplies of 4.5V to 11V or dual ±2.25V to ±5.5V supplies. Key electrical characteristics include an 85MHz small-signal bandwidth, a 500V/μs slew rate, and a 27MHz 0.1dB gain flatness. The device features rail-to-rail outputs, low differential gain/phase errors of 0.015%, and a disable mode consuming only 450μA per amplifier. It is housed in a 14-pin SO package.

Video Amps And Modules Procurement Notes

Verify the specific ordering suffix to confirm the tape and reel packaging format. Ensure the component meets RoHS compliance requirements for your manufacturing process. Confirm availability through authorized Analog Devices distributors as supply status may vary by region.

Video Amps And Modules Selection Notes

Select this part when triple-channel amplification is required alongside high-speed video processing capabilities. The disable feature makes it suitable for multiplexer applications where power consumption must be minimized during idle states. Ensure the load capacitance is managed with isolation resistors to maintain stability.

Video Amps And Modules Part Context

This component belongs to the MAX4389/MAX4390/MAX4392–MAX4396 series of ultra-small, low-cost op amps. The MAX4394 specifically provides three amplifiers with disable functionality, distinguishing it from non-disable variants like the MAX4392 or MAX4395 within the same family.

Video Amps And Modules Replacement Considerations

Direct replacements within the same family include the MAX4394EUD+T (14-pin TSSOP) for alternative packaging. Other family members like the MAX4392 or MAX4396 offer different channel counts but share similar electrical characteristics.

Video Amps And Modules FAQ

How does the disable function affect the output impedance?

When the disable pin is active, the amplifier enters a low-power state with a high output impedance of approximately 95kΩ.

What is the recommended approach for driving capacitive loads?

To prevent oscillation, place a small isolation resistor (typically 10Ω to 15Ω) between the amplifier output and the capacitive load.
