MAX4394EUD+T

Video Amps And Modules Overview

The MAX4394EUD+T is a triple-channel, unity-gain stable voltage-feedback operational amplifier from the MAX4389/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 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 14-pin TSSOP package.

Video Amps And Modules Procurement Notes

Verify the specific ordering suffix '+T' indicates tape and reel packaging when sourcing components. Confirm that the 'E' temperature grade corresponds to the -40°C to +85°C operating range required for your design environment. Ensure compatibility with the 14-pin TSSOP footprint during PCB layout planning.

Video Amps And Modules Selection Notes

Select this component for applications requiring high-speed signal processing with multiple channels in a limited space. The disable feature is advantageous for multiplexer designs where power conservation is critical. Consider the 5mA quiescent current per channel against total system power budgets and verify thermal dissipation capabilities within the TSSOP enclosure.

Video Amps And Modules Part Context

This part belongs to the MAX4389/MAX4390/MAX4392–MAX4396 family of ultra-small, low-cost op amps. The MAX4394 specifically denotes the triple-channel variant within this series. All members share similar high-speed architectures but differ in channel count and disable functionality availability.

Video Amps And Modules Replacement Considerations

Other members of the MAX4389/MAX4396 family may serve as alternatives depending on channel requirements. The MAX4393 offers dual channels with disable, while the MAX4396 provides four channels. Verify pinout compatibility and electrical specifications before substitution.

Video Amps And Modules FAQ

How does the disable function operate?

Connecting the DISABLE pin to VCC enables the amplifier. Driving the pin low places the output in a high-impedance state (95kΩ) while reducing quiescent current to approximately 450μA.

What is the input common-mode voltage range?

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