150-mW STEREO AUDIO POWER AMPLIFIER  
FEATURES  
DESCRIPTION  
150-mW Stereo Output  
The TPA122 is a stereo audio power amplifier pack-  
aged 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  
8-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.  
PC Power Supply Compatible  
– Fully Specified for 3.3-V and 5-V Operation  
– Operation to 2.5 V  
Pop Reduction Circuitry  
Internal Midrail Generation  
Thermal and Short-Circuit Protection  
Surface-Mount Packaging  
– PowerPAD™ MSOP  
THD+N when driving an 8-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-loads, the THD+N is reduced  
to less than 0.06% 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 0.01% at 1 kHz,  
and less than 0.02% across the audio band of 20 Hz  
to 20 kHz.  
– SOIC  
Pin Compatible With LM4880 and LM4881
