(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 TPA2012D2 is a stereo, filter-free Class-D audio  amplifier available in a WCSP or QFN package. The TPA2012D2 only requires two external components for operation.

 The TPA2012D2 features independent shutdown controls for each channel. The gain can be selected to 6, 12, 18, or 24 dB utilizing the G0 and G1 gain  select pins. High PSRR and differential architecture provide increased immunity to noise and RF rectifi- cation. In addition to these features, a fast startup  time and small package size make the TPA2012D2 an ideal choice for both cellular handsets and PDAs.

It  is capable of driving 1.4 W/Ch at 5 V or 720 mW/Ch at 3.6 V into 8 . It is also capable of driving 4 . The TPA2012D2 provides thermal and short circuit protection.
