† 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.
DescriptionThe 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- load with 40-mW output power from 3.3 V, THD+N is 0.08% at 1 kHz, and less than 0.2% across the audio band of 20 Hz to 20 kHz. For 30 mW into 32- 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.
