PA6021 Datasheet
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
* Steps from -40 dB ~ 20 dB
* – Fade Mode
* – -85-dB Mute Mode
* Differential Inputs
* 1-µA Shutdown Current (Typical)
* Headphone Mode
