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-Ω 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.
