TPA6021A4 - Stereo, Class-AB Audio Amplifier with Volume Control and Stereo Headphone Drive

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.
