TPA6021A4 - Texas Instruments

TPA6021A4 2-W STEREO AUDIO POWER AMPLIFIER

The TPA6021A4 is a stereo audio power amplifier that drives 2 W/channel of continuous RMS power into a 4-Ω 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 pow.
