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.
