MAX4550CWI

Analog Switches - Special Purpose Overview

The MAX4550CWI+ is a dual 4x2 analog and digital crosspoint switch manufactured by Analog Devices Inc. under the Maxim Integrated brand. It operates on a single supply voltage ranging from 2.7 V to 5.5 V. The device features a 28-pin SOIC package with surface-mount installation. Key electrical specifications include a maximum on-resistance of 5 Ω, typical off-isolation of 55 dB, and a charge injection characteristic suitable for video applications. It supports both analog and digital signal routing within its specified voltage limits.

Analog Switches - Special Purpose Feature Summary

• Dual 4x2 crosspoint architecture enabling flexible signal routing between four inputs and two outputs per section.
• Capable of handling both analog and digital signals across a wide single-supply voltage range.
• Low on-resistance ensures minimal signal attenuation during conduction.
• High off-isolation prevents signal leakage between unselected paths.

Analog Switches - Special Purpose Applications

• Audio and video signal routing systems
• Analog and digital crosspoint switching matrices
• Video distribution networks

Analog Switches - Special Purpose Procurement Notes

Verify component authenticity through authorized distributors or direct manufacturer channels due to discontinuation status. Confirm RoHS compliance details via official documentation as standard packaging may vary. Request original datasheets to validate pinout and electrical characteristics against specific design requirements before integration.

Analog Switches - Special Purpose Selection Notes

Evaluate the 28-pin SOIC footprint compatibility with existing PCB layouts. Ensure the 2.7 V to 5.5 V operating range aligns with system power rails. Consider the 55 dB off-isolation performance for crosstalk-sensitive applications. Verify that the 5 Ω on-resistance meets signal integrity standards for the intended frequency range.

Analog Switches - Special Purpose Part Context

This component belongs to the MAX4550 series of crosspoint switches designed for A/V applications. It is distinct from other Maxim Integrated switches like the MAX4534 or MAX4555 which offer different channel configurations or fault protection features. The CWI suffix indicates a commercial temperature range and SOIC-28 package variant.
