DESCRIPTION

The TPA6113A2 is a stereo audio power amplifier

packaged in an 8-pin SOIC package capable of

delivering 40 mW of continuous RMS power per channel into 16-Ω loads. Amplifier gain is externally

configured by means of two resistors per input

channel and does not require external compensation

for settings of 0 to 20 dB.

THD+N, when driving a 16-Ω load from 5 V, is 0.03%

at 1 kHz, and less than 1% across the audio band of 20 Hz to 20 kHz. For 32-Ω loads, the THD+N is

reduced to less than 0.02% at 1 kHz, and is less than

1% across the audio band of 20 Hz to 20 kHz.
