Working Principles

The SSM2301RMZ-REEL7 is a mono Class D audio amplifier that utilizes pulse-width modulation (PWM) to convert the input audio signal into a high-frequency square wave. This square wave is then filtered and amplified to produce the desired audio output. The Class D design ensures high efficiency by rapidly switching the output stage between fully on and fully off states, minimizing power dissipation.

Detailed Application Field Plans

• Portable audio devices: MP3 players, smartphones, tablets.
• Bluetooth speakers and wireless headphones.
• Automotive audio systems.
• Home theater systems and multimedia speakers.
• Gaming consoles and handheld gaming devices.
