MAX4550EWI+

Analog Switches - Special Purpose Overview

The MAX4550EWI+ is a serially controlled, dual 4x2 audio/video analog crosspoint switch manufactured by Analog Devices. It features two independent switch arrays with four inputs and two outputs each. The device operates on a single supply voltage ranging from +2.7V to +5.5V or dual supplies of ±2.7V to ±5.5V. Key electrical parameters include an on-resistance of 80Ω maximum, 10Ω maximum on-resistance matching between channels, and 5Ω maximum on-resistance flatness. Audio performance specifications include -110dB off-isolation at 20kHz, -95dB crosstalk at 20kHz, and 0.014% total harmonic distortion. Video performance includes -78dB off-isolation at 4MHz and -54dB crosstalk at 4MHz. The component utilizes a 2-wire I²C-compatible serial interface for control.

Analog Switches - Special Purpose Procurement Notes

Verify the specific ordering suffix against official documentation to confirm package type and temperature range. Confirm RoHS compliance status through manufacturer certificates. Check for end-of-life notifications or discontinuation notices prior to finalizing procurement plans.

Analog Switches - Special Purpose Selection Notes

Select this component when dual 4x2 routing with low distortion is required. Ensure the system supports the 2-wire I²C interface protocol. Verify that the operating voltage range matches the application's power supply constraints. Consider the wide SOIC-28 package dimensions for PCB layout compatibility.

Analog Switches - Special Purpose Part Context

This part belongs to the MAX4550/MAX4570 family of serially controlled crosspoint switches. The MAX4550 variant specifically uses a 2-wire I²C interface, whereas the MAX4570 uses a 3-wire SPI/MICROWIRE interface. Both share similar electrical characteristics and pinouts but differ in communication protocols.
