MAX4397SACTM+T

Audio Special Purpose Overview

The MAX4397SACTM+T is a dual-channel audio/video switch integrated circuit manufactured by Analog Devices Inc./Maxim Integrated. Designed for surface mount applications, it operates within a supply voltage range of 4.75V to 5.25V and supports an operating temperature range of 0°C to +70°C. The device features I2C interface control and is housed in a 48-WFQFN exposed pad package, specifically identified as 48-TQFN (7x7). It provides a specification value of 65dB, likely referring to channel isolation or crosstalk performance, and is intended for consumer audio applications.

Audio Special Purpose Feature Summary

• Dual-channel configuration for audio/video signal routing
• I2C digital interface for control
• Single 5V supply operation (4.75V ~ 5.25V)
• 48-TQFN (7x7) surface mount package

Audio Special Purpose Applications

• Consumer audio equipment

Audio Special Purpose Procurement Notes

This component is listed with a status of End-of-Life (EOL). Verification of current availability requires checking distributor databases directly, as standard manufacturing may have ceased. Ensure the specific suffix 'TM' corresponds to the Tape & Reel packaging variant when sourcing replacements.

Audio Special Purpose Selection Notes

Select this part for designs requiring dual-channel switching controlled via I2C. Verify that the PCB footprint matches the 48-TQFN (7x7) dimensions. Confirm that the required isolation/crosstalk performance meets the 65dB specification provided in the local data.

Audio Special Purpose Part Context

The MAX4397 belongs to the Maxim Integrated audio switch family. The 'SAC' prefix typically denotes the commercial temperature grade and specific package type, while 'TM' indicates the tape and reel packaging format. This distinguishes it from tube-packaged variants like the MAX4397SACTM+.

Audio Special Purpose Replacement Considerations

Due to the EOL status, direct substitutes should be sought from the same manufacturer's legacy portfolio or equivalent dual-channel I2C-controlled video switches. Verify pin compatibility and package dimensions before integration.
