MAX98360DENL+T

Audio Amplifiers Overview

The MAX98360DENL+T is a digital pulse-code modulation (PCM) input Class-D amplifier from Analog Devices. It operates on a single supply voltage ranging from 2.5V to 5.5V, delivering 3.2W of output power into a 4Ω load at 5V. The device features a total harmonic distortion plus noise of 0.009% and an efficiency of 92%. It supports sample rates from 8kHz to 96kHz with data word lengths of 16-bit, 24-bit, or 32-bit. The unit includes extensive click-and-pop reduction circuitry and robust short-circuit protection.

Audio Amplifiers Feature Summary

• Plug-and-play digital audio interface that automatically recognizes PCM and TDM clocking schemes without requiring I2C programming.
• Filterless spread-spectrum modulation scheme eliminates the need for external output filtering typically found in traditional Class-D devices.
• No external master clock (MCLK) signal required, reducing electromagnetic interference and board coupling issues.

Audio Amplifiers Applications

• Smart Speakers
• Notebook Computers
• IoT Devices
• Gaming Devices
• Tablets

Audio Amplifiers Procurement Notes

Verify the specific suffix 'DENL' against the manufacturer's current ordering guide to confirm package type and RoHS compliance status. Ensure the component matches the intended application requirements regarding gain settings and turn-on ramp times before finalizing procurement.

Audio Amplifiers Selection Notes

Select this part when a compact, low-cost digital amplifier is needed. It is suitable for applications requiring high efficiency and minimal external components. Consider the 1ms turn-on time characteristic if rapid startup is critical for the system design.

Audio Amplifiers Part Context

This component belongs to the MAX98360A/B/C/D family of tiny, cost-effective digital amplifiers. The 'D' variant specifically provides volume ramping during turn-on and turn-off. It is designed for space-constrained portable electronics where high audio quality and low EMI are essential.

Audio Amplifiers Replacement Considerations

The MAX98360BENI+T serves as a direct substitute within the same product family. Verify pinout compatibility and ensure the alternative variant meets the specific turn-on timing requirements of the target application.
