2-W STEREO AUDIO POWER

AMPLIFIER WITH ADVANCED

DC VOLUME CONTROL

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.

FEATURES

* 2 W Into 4-W speakers with external heatsink

* DC volume control with 2-dB

* Differential Inputs

* 1-µA Shutdown Current (Typical)
