EUA6021A
2.5-W Stereo Audio Power Amplifier
with Advanced DC Volume Control
DESCRIPTOIN
The EUA6021A 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.
FEATURES
z 2.5 W into 4-Speakers With External Heatsink
z DC Volume Control with 2-dB
Step from -40dB to 20dB
-Fade Mode
- -85-dB Mute Mode
z Differential Inputs
z 1 A Shutdown Current (Typical)
z Headphone Mode
z RoHS Compliant and 100% Lead (Pb)-Free
APPLICATIONS
z LCD Monitors
