(SOIC) The TPA122 is a stereo audio power amplifier packaged in either an 8-pin SOIC, or an 8-pin
PowerPADв„ў 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 …
