The Class-D audio amplifier is capable of delivering
6.1 W of peak power into a 4 Ω load at a battery
voltage of 3.6 V. TAS2110 is 83.5% efficient at 1 W
and consumes less than 1 uA in hardware shutdown
mode.
TAS2110 helps protect against system shutdown with
configurable brownout protection and VBAT tracking
peak voltage limiter, both of which are configurable.
The TAS2110 QFN package is compatible with 2
layer board designs.

3 Description
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 output boosts. The algorithms are
configured with PurePath Console GUI.
