Description

The TPA122 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 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. THD+N when driving an 8-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.
