Description

The TPA6017A2 is a stereo audio power amplifier in a 20-pin TSSOP thermally enhanced package capable of delivering 2 W of continuous RMS power per channel into 3- loads. Internal gain control minimizes the number of external components needed, simplifying the design, and freeing up board space for other features.

Amplifier gain is internally configured and controlled by way of two terminals (GAIN0 and GAIN1). Gain settings of 6 dB, 10 dB, 15.6 dB, and 21.6 dB (inverting) are provided.
