3 Description
The TPA2016D2 device is a stereo, filter-free Class-D
audio power amplifier with volume control, dynamic
range compression (DRC), and automatic gain
control (AGC). It is available in a 2.2 mm × 2.2 mm
DSBGA package and 20-pin QFN package.
The DRC and AGC function in the TPA2016D2 is
programmable through a digital I²C interface. The
DRC and AGC function can be configured to
automatically prevent distortion of the audio signal
and enhance quiet passages that are normally not
heard. The DRC and AGC can also be configured to
protect the speaker from damage at high power
levels and compress the dynamic range of music to fit
within the dynamic range of the speaker. The gain
can be selected from –28 dB to +30 dB in 1-dB steps.
The TPA2016D2 is capable of driving 1.7 W/Ch at 5
V or 750 mW/Ch at 3.6 V into 8-Ω load or 2.8 W/Ch
at 5 V or 1.5 W/Ch at 3.6 V into 4-Ω load. The device
features independent software shutdown controls for
each channel and also provides thermal and short-
circuit protection.
In addition to 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.
