The 5W output into 4Ω is the rated continuous power per channel.
Built-in short-circuit and thermal protection means the amplifier shuts down before the output stage or speaker is damaged. That's a reliability plus for designs where the load may be intermittent or the enclosure has limited airflow.
The TAS2559YZT is Active in production with no end-of-life notice. It is still available for new designs and production builds.
The TAS2559YZT delivers 5W into a 4Ω load from a single mono channel.
The TAS2559YZT is a Class D audio amplifier — a switching amplifier that offers high efficiency compared to linear Class AB designs.
