EUA6029 EUA6029 2.5-W Stereo Audio Power Amplifier with Advanced DC Volume Control DESCRIPTOIN FEATURES The EUA6029 EUA6029 is a stereo audio power amplifier that drives 2.5 W/channel of continuous RMS power into a 4- 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. 2.5 W into 4- Speakers With External Heatsink DC Volume Control with 2-dB Step from -40dB to 20dB -Fade Mode - -85-dB Mute Mode Differential Inputs 1A Shutdown Current (Typical) Headphone Mode RoHS Compliant and 100% Lead (Pb)-Free APPLICATIONS LCD Monitors DS6029 DS6029 Ver 1.0 Feb. 2008 1 EUA6029 EUA6029 Block Diagram DS6029 DS6029 Ver 1.0 Feb. 2008 2 EUA6029 EUA6029 Typical Application Circuit Figure 1.
