The TAS2555 device is a state-of-the-art Class-D audio amplifier which is a full system on a Chip (SoC). The device features a 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 maximizes 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 TAS2555 devices. Separate tuning for different speakers is supported allowing customers to add value while maintaining form factor designs. Additionally, the TAS2555 supports separate voice and audio tuning dynamically with ultra-low 15.9 µV ICN regardless of mode of operation making receiver/speaker implementations possible.
A Class-H boost converter generates the Class-D amplifier supply rail. When the audio signal only requires a lower Class-D output power, the boost improves system efficiency by deactivating and connecting VBAT directly to the Class-D amplifier supply. When higher audio output power is required, the multi-level boost quickly activates tracking the signal to provide the additional voltage to the load.
