MAX98360BEFB+T

Audio Amplifiers Overview

The MAX98360BEFB+T is a digital pulse-code modulation (PCM) input Class-D amplifier from the MAX98360 family. It operates on a single supply voltage ranging from 2.5V to 5.5V, delivering up to 3.2W of output power into a 4Ω load at 5V. The device features a quiescent current of approximately 2.2mA and supports sample rates from 8kHz to 96kHz with data word lengths of 16-bit, 24-bit, or 32-bit. It utilizes a 9-pin Wafer-Level Package (WLP) with a 0.4mm pitch.

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 components.
• No external master clock (MCLK) signal required, reducing electromagnetic interference and board pin count.
• Sophisticated edge-rate control and overshoot circuitry significantly reduce electromagnetic emissions.

Audio Amplifiers Applications

• Single Li-ion cell or 5V powered devices
• Smart speakers
• Notebook computers
• IoT devices
• Gaming devices
