„ DESCRIPTION
The PA6021 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 power.
To ensure a smooth transition between active and shutdown
modes, a fade mode ramps the volume up and down.
