TAS2559 Class-D Mono Audio Amplifier Texas Instruments TAS2559 Class-D Mono Audio Amplifier is a state-of-the-art Class-D audio amplifier which is a full system on a chip (SoC). The device features an ultra low-noise audio DAC and Class-D power amplifier which incorporates speaker voltage and current sensing feedback. An on-chip, low-latency DSP supports Texas Instruments SmartAmp speaker protection algorithms to maximize loudness while maintaining safe speaker conditions. The device can be used easily with any processor with an I2S output and stereo implementations are possible when using two TAS2559 devices. Separate tuning for different speakers is supported allowing customers to add value while maintaining form factor designs. Additionally, the TAS2559 supports separate voice and audio tuning dynamically with ultra-low 15.9µV ICN regardless of the mode of operation making receiver/speaker implementations possible.
