Descriptions:

The MAX9744ETH+T is a high-efficiency, Class D stereo audio amplifier designed for portable and battery-powered applications. It integrates a spread-spectrum modulation scheme to reduce EMI, eliminating the need for external filtering components. The device operates from a single supply and includes thermal and short-circuit protection.

Features:

• High Efficiency (Up to 90%)
• Spread-Spectrum Modulation for Reduced EMI
• No External LC Output Filters Required
• Thermal and Short-Circuit Protection
• Low Shutdown Current (<1µA)
• Wide Supply Voltage Range (4.5V to 14V)
• Stereo Speaker Driver (2 x 20W into 4Ω)
• Click-and-Pop Suppression

This amplifier is commonly used in portable speakers, docking stations, and other audio applications requiring high power efficiency and compact design.
