description  
The TPA102 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 8-Ω 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 an 8-Ω load from 5 V is 0.1% at 1 kHz, and less than 2% across the audio band of 20 Hz  
to 20 kHz. For 32-Ω loads, the THD+N is reduced to less than 0.06% at 1 kHz, and is less than 1% across the  
audiobandof20Hzto20kHz. For10-kΩ loads, theTHD+Nperformanceis0.01%at1kHz, andlessthan0.02%  
across the audio band of 20 Hz to 20 kHz.
