1.1 Description
The TPA2017D2 is a stereo, filter-free Class-D audio power amplifier with automatic gain control (AGC),
dynamic range compression (DRC). The AGC and DRC functions enhance the perceived audio loudness,
and at the same time prevent speaker damage from overdrive. Availability in the QFN package makes
TPA2017D2 an ideal choice for laptop and portable applications. The TPA2017D2 evaluation module
(EVM) is a complete, stand-alone audio board. It contains the TPA2017D2 QFN (RTJ) Class-D audio
power amplifier.
The TPA2017D2 evaluation module (EVM) is a complete stand-alone audio board. All components are
Pb-free.
