The LM4809LD from Texas Instruments is a high-performance audio amplifier designed to enhance the quality of sound in portable and low voltage applications.

• Power Output: 105mW of continuous average power into a 16Ω load with less than 1% distortion (THD+N) from a 5V power supply.
• Supply Voltage Range: 2.2V to 5.5V.
• Circuitry: pop and click suppression circuitry.
• Feature: Shutdown mode.
• Package: micro SMD package.
• PSRR: High power supply rejection ratio (PSRR).
• THD+N: Low total harmonic distortion plus noise (THD+N).
• Protection: thermal shutdown protection circuitry.
