DESCRIPTION
The TPA6110A2 is a stereo audio power amplifier packaged in an 8-pin PowerPAD MSOP package capable of
delivering 150 mW of continuous RMS power per channel into 16- loads. Amplifier gain is externally configured
by means of two resistors per input channel and does not require external compensation for settings of 1 to 10.
THD+N when driving a 16- 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- 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-k 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.
