150-mW Stereo Headphone Audio Amplifier with Differential Input

150-mW Stereo Headphone Audio Amplifier with Differential Input - TPA6112A2
Datasheet
 

Description

The TPA6112A2 is a stereo audio power amplifier with differential inputs packaged in a 10-pin PowerPAD MSOP package capable of delivering 150 mW of continuous RMS power per channel into 16- 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 16- 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- 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. For 10-k loads, the THD+N performance is 0.005% at 1 kHz, and less than 0.5% across the audio band of 20 Hz to 20 kHz.
