MAX4399CTK+T

Audio Special Purpose Overview

The MAX4399CTK+T is a dual-channel audio/video switch manufactured by Analog Devices Inc. under the Maxim Integrated brand. It operates within a supply voltage range of 5V to 12V and supports an operating temperature range of 0°C to 70°C (TA). The device features I2C interface control and provides an isolation specification of 86dB. Packaged in a 68-TQFN (10x10) exposed pad case with surface mount mounting type, it is designed for consumer audio applications.

Audio Special Purpose Feature Summary

• Dual-channel configuration for audio/video switching
• I2C digital control interface
• 86dB isolation specification
• Wide supply voltage range: 5V to 12V

Audio Special Purpose Applications

• Consumer audio systems

Audio Special Purpose Procurement Notes

Verify the 68-TQFN package dimensions and exposed pad thermal requirements against the target PCB layout. Confirm that the I2C address configuration matches the system bus design. Ensure the operating temperature range of 0°C to 70°C meets the environmental constraints of the final assembly. Check for any specific handling precautions associated with the Tape & Reel packaging format during surface mount placement.

Audio Special Purpose Selection Notes

Select this component when a dual-channel switch with I2C control is required for consumer audio paths. The 5V to 12V supply range accommodates various system power rails. The 86dB isolation figure should be validated against the specific crosstalk or leakage requirements of the audio signal chain. The 68-TQFN package necessitates adequate thermal relief on the PCB due to the exposed pad design.

Audio Special Purpose Part Context

This part belongs to the Maxim Integrated line of specialized audio and video switching integrated circuits. It serves as a digital-controlled multiplexer solution for routing multiple audio sources to outputs in compact consumer electronics. The T suffix indicates tape and reel packaging for automated assembly processes.
