MAX9736AETJ+T

Audio Amplifiers Overview

The MAX9736AETJ+T is a mono/stereo high-power Class D audio amplifier from Analog Devices/Maxim Integrated. It delivers up to 2x15W into 8Ω loads or 1x30W into a 4Ω load in stereo and mono modes, respectively. Operating from an 8V to 28V supply range, it achieves up to 88% efficiency at 12V. The device features pin-selectable filterless spread-spectrum modulation for low EMI or classic PWM modulation. It includes comprehensive click-and-pop reduction, independent dual paths, and operates over a -40°C to +85°C temperature range.

Audio Amplifiers Feature Summary

• Pin-selectable modulation schemes allow switching between filterless spread-spectrum mode for low EMI and classic PWM mode optimized for LC filters.
• Integrated thermal and output current protection safeguards the device during operation.
• Comprehensive click-and-pop reduction circuitry minimizes audible noise during shutdown or mute transitions.
• Mono configuration enables parallel channel operation for higher power output while providing an uncommitted operational amplifier.

Audio Amplifiers Applications

• LCD/PDP/CRT monitors
• LCD/PDP/CRT TVs
• MP3 docking stations
• Notebook PCs
• PC speakers

Audio Amplifiers Procurement Notes

Verify that the ordering suffix 'T' indicates tape-and-reel packaging as specified in the manufacturer's documentation. Confirm the specific variant (MAX9736A) matches the required power output specifications. Ensure compatibility with the 32-pin TQFN package dimensions and thermal requirements for the target PCB layout.

Audio Amplifiers Selection Notes

Select this component when high efficiency and minimal external filtering are required. The MAX9736A is suitable for applications needing up to 30W mono or 15W per channel stereo output. Consider the pin-selectable modulation options based on EMI constraints and whether an LC filter is present in the design.

Audio Amplifiers Part Context

The MAX9736 series includes variants A, B, and D, differentiated by output power capabilities. The MAX9736A provides the highest power output among the family. These amplifiers are designed to replace traditional Class AB amplifiers, offering similar audio quality with significantly improved thermal efficiency and reduced board space requirements.

Audio Amplifiers Replacement Considerations

Compatible substitutes within the same family include MAX9736BETJ+T and MAX9736DETJ+T. Verify that the alternative variant meets the specific power delivery requirements of the application, as the B and D variants offer lower output power compared to the A variant.
