MAX98363CEWL+T

Audio Amplifiers Overview

The MAX98363CEWL+T is a tiny, low-cost, SoundWire input Class D mono amplifier providing industry-leading Class AB audio performance with Class D efficiency. It features an internal tone generator, interrupt control, and selectable slew-time settings for the SoundWire data output PHY. The device supports MIPI SoundWire v1.2-compatible digital interfaces for audio and control data. Operating on a single supply of 2.5V to 5.5V, it delivers 3.2W output power into a 4Ω load at 5V with THD+N ≤ 10%. Key electrical parameters include 12.8μVRMS output noise, 108.5dB dynamic range, and 0.014% THD+N at 1kHz. It operates within a temperature range of -40°C to +85°C.

Audio Amplifiers Procurement Notes

Verify the specific suffix 'CEWL' against official Analog Devices documentation to confirm package type and RoHS status. Ensure DVDDIO requirements match the C/D variant specifications if external power is used. Confirm availability through authorized distributors as stock levels fluctuate. Validate that the ordering code matches the exact pinout and thermal characteristics required for the target PCB design.

Audio Amplifiers Selection Notes

Select this component for applications requiring high audio fidelity combined with low power consumption in space-constrained designs. The filterless spread-spectrum modulation reduces BOM cost by eliminating large output inductors. Consider the internal LDO option for simplified power management or external DVDDIO for lower quiescent current. Ensure the host processor supports the MIPI SoundWire protocol for proper integration.

Audio Amplifiers Part Context

The MAX98363 belongs to Maxim Integrated's line of compact, cost-effective Class D amplifiers designed for mobile and portable electronics. It utilizes a novel pinout to enable a cost-effective wafer-level package (WLP) without expensive in-pad vias. This family emphasizes high efficiency and low electromagnetic interference, making it suitable for battery-powered devices where audio quality and board real estate are critical constraints.

Audio Amplifiers Replacement Considerations

Check for MAX98363A/B variants which utilize an internal LDO for DVDDIO, offering different quiescent power profiles compared to the C/D variants. Verify compatibility with existing SoundWire controller firmware when substituting between revisions or similar models in the MAX9836x series.
