FUNCTIONAL BLOCK DIAGRAM
DESCRIPTION
The TPA112 is a stereo audio power amplifier packaged in an 8-pin Power PAD™ MSOP package capable of delivering 150 m W 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 pensation for settings of 1 to 10.
THD+N when driving an 8-Ω load from 5 V is 0.1% at 1 k Hz, and less than 2% across the audio band of 20 Hz to 20 k Hz. For 32-Ω loads, the THD+N is reduced to less than 0.06% at 1 k Hz, and is less than 1% across the audio band of 20 Hz to 20 k Hz. For 10-kΩ loads, the THD+N...
