Product Summary

The TPA122DR is a stereo audio power amplifier packaged 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 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-W load from 5 V is 0.1% at 1 kHz, and less than 2% across the audio band of 20, PowerPAD MSOP Hz to 20 kHz. For 32-W loads, the TPA122DR 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.
