DescriptionThe TPA2016D2 deviceisa stereo, filter-free Class-D
audio power amplifier with volume control, dynamic
range compression (DRC), and automatic gain
control (AGC).Itis availableina 2.2 mm× 2.2 mm
DSBGA package and 20-pin QFN package.
The DRC and AGC functionin the TPA2016D2is
programmable througha digitalI2C interface. The
DRC and AGC function can be configured to
automatically prevent distortionof the audio signal
and enhance quiet passages that are normally not
heard. The DRC and AGC can also be configuredto
protect the speaker from damage at high power
levels and compress the dynamic rangeof musictofit
within the dynamic rangeof the speaker. The gain
canbe selected from –28 dBto +30 dBin 1-dB steps.
The TPA2016D2is capableof driving 1.7 W/Chat5or 750 mW/Chat 3.6V into 8-Ω loador 2.8 W/Ch5Vor 1.5 W/Chat 3.6V into 4-Ω load. The device
features independent software shutdown controls for
each channel and also provides thermal and short-
circuit protection. additionto these features,a fast start-up time and
small package size make the TPA2016D2 an ideal
choice for cellular handsets, PDAs, and other
portable applications.
Device Information(1)(1) Forall available packages, see the orderable addendumat
