The TPA6101A2 is a stereo audio power amplifier packaged in an 8-pin SOIC package, an 8-pin MSOP package, or a 15-ball BGA package, capable of delivering 50 mW of continuous RMS power per channel into 16- loads. Amplifier gain is internally set to 2 dB (inverting) to save board space by eliminating six external resistors.

The TPA6101A2 is optimized for battery applications because of its low supply current, shutdown current, and THD+N. To obtain the low supply voltage range, the TPA6101A2 biases BYPASS to VDD/4.

When driving a 16- loads, the THD+N is reduced to less than 0.06% at 1 kHz, and is less than 0.3% across the audio band of 20 Hz to 20 kHz.
