TAS2110 - Texas Instruments

TAS2110 6.1-W Digital Input Audio Class-D Amplifier

The TAS2110 is a digital input Class-D audio amplifier with an algorithmically controlled, 11V Class-H boost in a QFN package. The look-ahead algorithms optimize boost voltage levels to match the output of the audio signal. This provides all the power needed for peak output while reducing the average power consumption significantly compared to constant outpu.
