TPA6021A4 - 2-W STEREO AUDIO POWER AMPLIFIER

General Description

The TPA6021A4 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-Ω Speakers With External Heatsink.
  • DC Volume Control With 2-dB Steps from -40 dB to 20 dB.
  • Fade Mode.
  • -85-dB Mute Mode.
  • Differential Inputs.
  • 1-µA Shutdown Current (Typical).
  • Headphone Mode.
