description
GND
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-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.
