PA6021 - 2-W STEREO AUDIO POWER AMPLIFIER

General 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.

Key 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.

UNISONIC TECHNOLOGIES CO., LTD PA6021 2-W STEREO AUDIO POWER AMPLIFIER WITH ADVANCED DC VOLUME CONTROL CMOS IC „ 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.
