MC6019
3W Stereo Audio Power Amplifier with Advanced
DC Volume Control
General Description
The MC6019 is a stereo audio power amplifier
that drives 3 W/channel of continuous RMS power
into a 3-W load. Advanced dc volume control
minimizes external components and allows BTL
(speaker) volume control and SE (headphone)
volume control. Notebook and pocket PCs benefit
from the integrated feature set that minimizes
external components without sacrificing
functionality.
To simplify design, the speaker volume level is
adjusted by applying a dc voltage to the VOLUME
Terminal, Likewise, the delta between speaker
volume and headphone volume can be adjusted
by applying a dc voltage to the SEDIFF terminal.
To avoid an unexpected high volume level through
the headphones, a third terminal, SEMAX, limits
the headphone volume level when a dc voltage is
applied. Finally, to ensure a smooth transition
between active and shutdown modes, a fade
mode ramps the volume up and down.
