MAX4221CSE+

Video Amps And Modules Overview

The MAX4221CSE+ is a dual SPDT buffered video switch manufactured by Analog Devices Inc. (Maxim Integrated). It operates from ±5V supplies and features a 330MHz -3dB bandwidth with 0.1dB gain flatness to 150MHz. The device provides a 700V/µs slew rate, 0.01° differential phase error, and 0.01% differential gain error. It includes on-board control logic for channel selection, offers high-impedance outputs when disabled, and minimizes switching glitches to 13mVp-p.

Video Amps And Modules Procurement Notes

Verify the component matches the specific package type and temperature range indicated in the datasheet ordering information. Confirm that the suffix corresponds to the standard plastic narrow SOIC package variant. Ensure compatibility with the required supply voltage and logic interface levels before finalizing procurement.

Video Amps And Modules Selection Notes

Select this component for applications requiring wideband video signal routing with minimal distortion. The dual SPDT configuration allows independent control of two channels within a single package. Consider the high input impedance and low output capacitance for maintaining signal integrity in large switching matrices.

Video Amps And Modules Part Context

This part belongs to the MAX4111/MAX4121/MAX4221 family of wideband video switches designed for broadcast-quality signal processing. These devices utilize a proprietary ultra-high frequency complementary bipolar process to achieve high bandwidth and low capacitance characteristics suitable for demanding video applications.

Video Amps And Modules Replacement Considerations

Compatible substitutes include the MAX4111 and MAX4121 variants within the same family. Verify pinout compatibility and ensure the replacement meets the required 330MHz bandwidth specifications for the intended application.

Video Amps And Modules FAQ

How does the MAX4221 handle make-before-break switching?

The device uses make-before-break switching to reduce noise and glitches. The input buffers provide constant high input impedance, preventing the switching action from feeding back to the input.

What is the purpose of the disable function?

The disable function puts the outputs into a high-impedance state and reduces the operating current to only 250µA per channel.
