MAX4397SCTM+

Audio Special Purpose Overview

The MAX4397SCTM+ is a dual-channel audio/video switch manufactured by Analog Devices Inc. under the Maxim Integrated brand. It operates on a single 4.75V to 5.25V supply and features an I2C interface for control. The device provides 65dB of isolation and is housed in a 48-TQFN (7x7) package with an exposed pad. Designed for surface mount installation, it functions within a temperature range of 0°C to 70°C. This component is classified as an audio special purpose integrated circuit intended for consumer audio applications.

Audio Special Purpose Feature Summary

• Dual-channel architecture for audio/video signal routing
• I2C serial interface for digital control
• 65dB isolation specification
• Single 5V supply operation (4.75V ~ 5.25V)

Audio Special Purpose Applications

• Consumer audio systems

Audio Special Purpose Procurement Notes

Verify the specific suffix 'SCTM+' against official documentation to confirm package type and tape/reel configuration. Confirm current availability status as product lifecycle data may indicate obsolescence or limited stock. Ensure the 48-WFQFN exposed pad thermal requirements are met in the final PCB layout design.

Audio Special Purpose Selection Notes

Select this component when a dual-channel switch with I2C control is required for 5V consumer audio circuits. Verify that the 0°C to 70°C operating temperature range meets the environmental constraints of the target application. Consider the 48-TQFN footprint dimensions during mechanical design integration.

Audio Special Purpose Part Context

This part belongs to the Maxim Integrated audio/video switch portfolio, now part of Analog Devices Inc. It serves as a specialized IC for managing multiple audio sources in compact consumer electronics. The 48-pin TQFN package allows for high-density board layouts while maintaining signal integrity through dedicated isolation specifications.

Audio Special Purpose Replacement Considerations

Check for direct pin-compatible alternatives from the same manufacturer family if the MAX4397SCTM+ is unavailable. Verify that any substitute maintains the 4.75V-5.25V supply range and I2C compatibility.
