MAX9741ETN+D

Audio Amplifiers Overview

The MAX9741ETN+D is a stereo Class D audio power amplifier delivering 12W continuous output into 8Ω loads. It operates on a single supply from 10V to 25V with 0.1% THD+N and >100dB SNR. The device features spread-spectrum mode for low EMI, differential inputs, and comprehensive click-and-pop suppression. It includes short-circuit and thermal-overload protection and is housed in a 56-pin TQFN package.

Audio Amplifiers Feature Summary

• Spread-spectrum modulation reduces radiated EMI emissions
• Differential input architecture minimizes common-mode noise
• Comprehensive click-and-pop suppression eliminates audible transients
• Integrated short-circuit and thermal-overload protection

Audio Amplifiers Applications

• LCD/PDP TVs
• CRT TVs
• PC Speakers

Audio Amplifiers Procurement Notes

Verify the specific suffix ETN+D corresponds to the 56-pin TQFN-EP package and -40°C to +85°C temperature range. Confirm lead-free status (+) matches project requirements. Ensure the ordering code aligns with the manufacturer's current datasheet revision to avoid pinout or functional discrepancies.

Audio Amplifiers Selection Notes

Select this component for high-efficiency stereo audio applications requiring minimal board space. The differential inputs are suitable for noisy digital environments. Consider the spread-spectrum mode if EMI compliance is critical without bulky filters. Verify thermal management capabilities via the exposed paddle for sustained high-power operation.

Audio Amplifiers Part Context

This part belongs to Maxim Integrated's Class D amplifier family, designed to offer Class AB performance with Class D efficiency. It utilizes proprietary modulation schemes to eliminate traditional EMI suppression filters, making it ideal for space-constrained consumer electronics where audio fidelity and electromagnetic compatibility are paramount.

Audio Amplifiers Replacement Considerations

Check for direct pin-compatible alternatives within the same product family that may offer updated packaging or extended temperature ranges. Verify that any substitute maintains the 12W per channel output capability and supports the required 10V to 25V supply voltage range.
