TAS2557 Class-D Audio Amplifier

Texas Instruments TAS2557 Class-D Audio Amplifier is a complete system on a Chip (SoC) that features an ultra-low-noise audio DAC and Class-D power amplifier. These features incorporate 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. Stereo implementations are possible when using two TAS2557 devices. Separate tuning for different speakers is supported, allowing customers to add value while maintaining form factor designs. The TAS2557 also dynamically supports distinct voice and audio tuning with ultra-low 15.9µV ICN regardless of the mode of operation, making receiver/speaker implementations possible.
