MAX98365CEWC+

Audio Amplifiers Overview

The MAX98365CEWC+ is a digital input Class-D amplifier from Analog Devices/Maxim Integrated. It delivers 13.8W into an 8Ω load at 14V and 17.6W into a 6Ω load at 14V. The device operates on a wide PVDD supply range of 3V to 14V with a VDD range of 1.71V to 5.5V. It features a quiescent power consumption of 30mW, 92.7% efficiency at 7.0W output, and a dynamic range of 111.5dB. The unit supports sample rates from 8kHz to 192kHz and utilizes a 12-bump WLP package measuring 1.21mm x 1.78mm.

Audio Amplifiers Feature Summary

• Plug-and-play digital interface automatically recognizes PCM and TDM clocking schemes without I2C programming
• Filterless spread-spectrum modulation eliminates the need for external output filtering components
• No master clock (MCLK) required, reducing EMI and board coupling issues while lowering pin count
• Advanced edge-rate limiting and overshoot control circuitry significantly reduces electromagnetic interference

Audio Amplifiers Applications

• Smart Speakers
• Notebook Computers
• IoT Devices
• Gaming Devices (Audio and Haptics)
• Smartphones

Audio Amplifiers Procurement Notes

Verify the specific CEWC suffix against the manufacturer's official ordering guide to confirm RoHS compliance and lead-free status. Ensure the component matches the 12-bump WLP physical footprint and thermal resistance specifications. Confirm that the datasheet revision aligns with your design requirements before finalizing procurement.

Audio Amplifiers Selection Notes

Select this model when high power output up to 14V is required in a minimal footprint. It is suitable for designs needing fast turn-on times or volume ramping depending on the subvariant. Consider its plug-and-play nature if software configuration overhead must be minimized. Evaluate the filterless operation benefits against strict EMI constraints.

Audio Amplifiers Part Context

This component belongs to the MAX98365 family of tiny, cost-effective digital amplifiers. It provides industry-leading Class-AB audio performance combined with Class-D efficiency. The series includes variants with different turn-on behaviors and interface configurations, all sharing the same compact WLP package and broad supply voltage capabilities.

Audio Amplifiers Replacement Considerations

Substitute only with other MAX98365 variants (e.g., MAX98365A/B/C/D) confirmed by the manufacturer. Verify pinout compatibility and electrical parameter alignment before implementation.
