The TPA6111A2 is a stereo audio power amplifier packaged in either an 8-pin SOIC or an
8-pin PowerPAD MSOP package capable of delivering 150 mW of continuous RMS power per channel into
16-Ω loads. Amplifier gain is externally configured by means of two resistors per input channel and
does not require external compensation for settings of 0 to 20 dB.
THD+N, when driving a 16-Ω load from 5 V, is 0.03% at 1 kHz, and less than 1% across the
audio band of 20 Hz to 20 kHz. For 32-Ω loads, the THD+N is reduced to less than 0.02% at 1 kHz,
and is less than 1% across the audio band of 20 Hz to 20 kHz. For 10-kΩ loads, the THD+N
performance is 0.005% at 1 kHz, and less than 0.5% across the audio band of 20 Hz to 20 kHz.
