DESCRIPTION
The TPA6101A2 is a stereo audio power amplifier packaged in either an 8-pin SOIC package or an 8-pin MOSP 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 6 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.
