General Description

The TPA2017D2 (sometimes referred to as TPA2017) is a stereo, filter-free Class-D audio power amplifier with SmartGainTM dynamic range compression (DRC), automatic gain control (AGC), and noise gate.

It is available in a 4 mm x 4mm QFN package.

SmartGainTM functions are configured to automatically prevent distortion of the audio signal and enhance quiet passages that are normally not heard.
