The TPA2017D2 (sometimes referred to as TPA2017) is a stereo, filterless Class D SmartGain™ dynamic range compression (GOLD), automatic gain control (AGC), noise gate audio power amplifier. It comes in a 4mm x 4mm QFN package.

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