MAX4259EEE

Video Amps And Modules Overview

The MAX4259EEE is a wideband, 2-channel, noninverting video amplifier with input multiplexing. It operates from ±5V supplies and drives ±2.5V signals into 50Ω or 75Ω loads. Optimized for gains of two (6dB) or more, it features a 250MHz -3dB bandwidth, 1000V/µs slew rate, and 20ns settling time to 0.1%. The device includes address latching and high-impedance output disabling, allowing integration into large switching arrays. It offers low differential gain and phase errors of 0.01%/0.02°.

Video Amps And Modules Procurement Notes

Verify the specific package type against the datasheet pinout diagrams. Confirm that the application circuit utilizes appropriate surface-mount components and layout techniques to maintain stability. Ensure power supply bypassing meets the recommended specifications for high-frequency performance.

Video Amps And Modules Selection Notes

Select this component when a gain of two or higher is required for video applications. The MAX4259 differs from the MAX4159 by being optimized for higher closed-loop gains rather than unity gain. Verify that the system requires address latching and output disabling features for proper array integration.

Video Amps And Modules Part Context

This device belongs to the MAX4158/MAX4159/MAX4258/MAX4259 family of wideband video multiplexer-amplifiers. While the MAX4159 is optimized for unity gain, the MAX4259 variant provides superior AC performance at gains of two or greater. Both share similar packaging options including 16-pin QSOP.

Video Amps And Modules FAQ

How does the MAX4259 differ from the MAX4159?

The MAX4259 is optimized for closed-loop gains of two (6dB) or greater, whereas the MAX4159 is optimized for unity gain (0dB). The MAX4259 offers a 250MHz bandwidth compared to the MAX4159's 350MHz.

What is the purpose of the EN pin on the MAX4259?

The EN pin controls the output state. Connecting it to logic high places the output in a high-impedance state, while connecting it to logic low enables normal operation.
