DESCRIPTION
The TPA112 is a stereo audio power amplifier pack-
aged in an 8-pin PowerPAD™ MSOP package
capable of delivering 150 mW of continuous RMS
power per channel into 8-W loads. Amplifier gain is
externally configured by means of two resistors per
input channel and does not require external compen·
sation 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
Hz to 20 kHz. For 32-W 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-kW
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.
