EUA6029

EUA6029 2.5-W Stereo Audio Power Amplifier with Advanced DC Volume Control DESCRIPTOIN The EUA6029 is a stereo audio power amplifier that drives 2.5 W/channel of continuous RMS power into a 4-Ω load. 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.
