Internal Gain Control, Which Eliminates
External Gain-Setting Resistors
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.

Low Supply Current . . . 6-mA Typical
Depop Circuitry
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.
