MAX4394ESD+T

Video Amps And Modules Overview

The MAX4394ESD+T is a triple-channel, unity-gain stable video operational amplifier manufactured by Analog Devices. It operates from single 4.5V to 11V or dual ±2.25V to ±5.5V supplies. Key electrical specifications 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 high output drive capability of ±50mA. It includes a disable mode that reduces quiescent current to 450μA per amplifier while setting outputs to high impedance.

Video Amps And Modules Procurement Notes

Verify the specific package type and tape-and-reel configuration against the official manufacturer datasheet before procurement. Ensure the ordering suffix matches the required packaging format. Confirm availability status directly with authorized distributors as supply conditions may vary.

Video Amps And Modules Selection Notes

Select this component for applications requiring high-speed video signal amplification with precise gain flatness. Consider the triple-channel configuration and integrated disable feature for power management in multi-channel systems. Evaluate thermal dissipation requirements based on the SOIC-14 package characteristics and operating temperature range.

Video Amps And Modules Part Context

The MAX4394 belongs to the MAX4389/MAX4390/MAX4392–MAX4396 family of ultra-small, low-cost op amps. This family combines high-speed performance with rail-to-rail outputs and disable modes. The MAX4394 specifically provides three amplifiers in a single package, distinguishing it from single, dual, and quad variants within the same series.

Video Amps And Modules Replacement Considerations

Consult the official selector guide for direct functional equivalents within the MAX4389–MAX4396 family. Verify pin compatibility and channel count when considering alternatives such as the MAX4395 or MAX4396.

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 outputs are set to a high-impedance state with an output resistance of approximately 95kΩ, while the quiescent supply current drops to 450μA per amplifier.

What is the typical differential gain and phase error?

The device exhibits low differential gain and phase errors of 0.015% and 0.015 degrees, respectively, making it suitable for NTSC/PAL video applications.
