MAX98363AEWL+T

Audio Amplifiers Overview

The MAX98363AEWL+T is a SoundWire input Class D mono amplifier providing AB-class audio performance with D-class efficiency. It operates on a single supply of 2.5V to 5.5V, delivering 3.2W output power into a 4Ω load at 5V with THD+N ≤ 10%. The device features a 9-bump WLP package (1.528mm x 1.528mm) and supports MIPI SoundWire v1.2. Key electrical parameters include 12.8μVRMS output noise, 108.5dB dynamic range, and 0.014% THD+N at 1kHz. Quiescent power consumption is 12.3mW with external DVDDIO.

Audio Amplifiers Feature Summary

• Integrates an internal tone generator for factory testing or system boot-up sounds.
• Utilizes filterless spread-spectrum modulation to eliminate the need for traditional output filtering components.
• Features programmable slew-rate control on the SoundWire data output PHY to minimize electromagnetic interference.
• Includes sophisticated edge-rate limiting and overshoot control circuitry for enhanced EMI planning.

Audio Amplifiers Applications

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

Audio Amplifiers Procurement Notes

Verify the specific suffix AEWL against the manufacturer's current ordering guide to confirm pinout compatibility and RoHS status. Ensure the design accommodates the 9-bump WLP footprint requirements as specified in application note 1891. Confirm that the host system provides the necessary 1.8V nominal voltage supply for the digital interface.

Audio Amplifiers Selection Notes

Select this component for designs requiring high audio fidelity in space-constrained mobile applications. The integrated SoundWire interface simplifies digital audio connections compared to analog inputs. Consider the internal LDO option if external DVDDIO generation is not feasible, noting the slight difference in quiescent power consumption between A/B and C/D variants.

Audio Amplifiers Part Context

This device belongs to the MAX98363 family of tiny, cost-effective amplifiers designed for portable electronics. It combines the efficiency of Class D topology with the low distortion characteristics typically associated with Class AB amplifiers. The family supports multiple unique addresses via configurable ADDR pins, allowing up to ten devices on a single SoundWire data lane.

Audio Amplifiers Replacement Considerations

Direct replacements within the same family include MAX98363BEWL+T, MAX98363CEWL+T, and MAX98363DEWL+T. Selection depends on whether the design utilizes an internal or external DVDDIO supply, as these variants differ in power management architecture while maintaining identical acoustic performance.
