The TAS2560 is a low-power, high-performance, digital input, boosted Class-D Audio
amplifier that can be easily implemented in both mono and stereo (x2) applications. The device
features an ultra low-noise audio DAC and Class-D power amplifier which incorporates speaker
voltage and current sensing feedback for use with speaker protection algorithms.
A Class-H boost converter generates the Class-D amplifier supply rail. When the audio
signal requires only a lower Class-D output power, system efficiency is improved by deactivating
the boost and connecting VBAT directly to the Class-D amplifier supply. When higher audio output
power is required, the multi-level boost re-activates tracking the signal to provide the additional
voltage to the load.
A configurable on-chip Battery Guard system reduces the audio output power during the
periods of low battery voltage to minimize the battery dropping below system brownout conditions.
Additionally, faults such as brownout, over-current, and over-temperature can be reported back to
the host processor using the IRQ pin. All protection statuses are available via a register
