Description

The TPA6021A4 is a stereo audio power amplifier that drives 2 W/channel of continuous RMS power into a 4-load when utilizing a heat sink. Advanced dc volume control minimizes external components and allows BTL (speaker) volume control and SE (headphone) volume control. The 20-pin DIP package allows for the use of a heatsink which provides higher output power. To ensure a smooth transition between active and shutdown modes, a fade mode ramps the volume up and down.
