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-Ω 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.
