The TPA2017D2 (sometimes called TPA2017) is a stereo, filterless Class D SmartGain Dynamic Range™ Compression (Gold), Automatic Gain Control (AGC), Noise Gated Audio Power Amplifier. It is available in a 4 mm x 4 mm QFN package.

The SmartGain™ function is configured to automatically prevent distortion and intensification of the audio signal, which is often not heard of on calm channels. SmartGain™ is a joint AGC DRC and limiter that prevents damage to the dynamic range of the speaker and compressed sound or music at high power levels to match the dynamic range of the speaker. SmartGain™ DRC, limiter, noise gate feature can be enabled or disabled. The TPA2017D2 (TPA2017) is the ability to drive 1.
