(1) Stresses beyond those listed under "absolute maximum ratings" may cause permanent damage to the device. These are stress ratings only, and functional operation of the device at these or any other conditions beyond those indicated under "recommended operating conditions" is not implied. Exposure to absolute-maximum-rated conditions for extended periods may affect device reliability.

The TPA2016D2 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 x 2.2 mm WCSP package.

The DRC/AGC function in the TPA2016D2 is programmable via a digital I²C interface. The DRC/AGC function can be configured to automatically prevent distortion of the audio signal and enhance quiet passages that are normally not heard. The DRC/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 2  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 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.
