DESCRIPTION
The TPA6110A2 is a stereo audio power amplifier packaged in an 8-pin PowerPADMSOP 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-kloads, 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.

These devices have limited built-in ESD protection. The leads should be shorted together or the device placed in conductive foam
during storage or handling to prevent electrostatic damage to the MOS gates.
