DESCRIPTION
The TPA6111A2 is a stereo audio power amplifier
packaged in either an 8-pin SOIC or an 8-pin
PowerPAD鈩?MSOP package capable of delivering
150 mW of continuous RMS power per channel into
16-鈩?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-鈩?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-鈩?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鈩?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.
