Technical Specifications (Typical):

Specific technical specifications for the R2S11004FT are available in the Renesas datasheet. Typical specifications include an output power ranging from 1W to 3W into an 8-ohm load, a THD+N (Total Harmonic Distortion + Noise) figure of less than 0.1%, and a supply voltage range typically between 2.5V and 5.5V.

The integrated protection circuits usually encompass short-circuit protection, overcurrent protection, and thermal shutdown. These features are designed to prevent damage to the amplifier and connected components during fault conditions. The standby function enables reduced power consumption when the amplifier is not actively amplifying audio. The small surface-mount package allows for efficient use of board space and automated assembly.

In summary, the R2S11004FT is a compact, efficient, and reliable audio power amplifier suitable for a wide range of portable audio applications.
